Didcot power station 3 cooling towers demolished
Disused Three cooling towers at Oxford shire are demolished on Sunday morning The blast, conducted with more than 180 kg of explosives, flattened 36,000 tonnes of material in seconds and was streamed live online .
Hundreds of people gathered to watch the towers come down at 05:01 BST, despite warnings of a huge dust cloud.
The decision to carry out the demolition before sunrise was criticized by some residents.
The coal-fired power station ceased generating in March last year after dominating the skyline around the town since 1970.

Abu Dhabi: After 100 days of showcasing some of history’s most important artifacts, the History of the World in 100 Objects exhibition will finally draw to a close on August 1.
Since its launch on April 23, the gallery has taught visitors about the origins of humanity with items dating as far back as 1.7 million years ago. It has also given guests a glimpse into some of the iconic moments that have shaped the history of the world.
The exhibition represents some of the themes that will be seen at the Zayed National Museum, which is expected to open its doors in 2016.

History of the World in 100 Objects exhibition going to close on August 1

            Top 7 World's Threatened & Stunning Beaches


1.Magdalen Islands, Quebec


The approximately 13,000 residents of Magdalen Islands have watched intensifying natural forces threaten the boundaries of their home in recent years. “Warmer winters and fiercer storms, rising seawaters and the slow sinking of the islands are responsible for an alarming loss of coastline, and the erosion appears to be accelerating,” reports Canadian Geographic.

2. Miami Beach, Florida


In May 2014, a new scientific report on global warming, the National Climate Assessment, named Miami as one of the cities most vulnerable to severe damage as a result of rising sea levels.


3.Seychelles, Indian Ocean



In the past decade, the rising sea level has taken a bite out of this spectacular strip of shore in the Indian Ocean northeast of Madagascar. “Rising temperatures and the melting of polar ice caps are blamed for raising ocean levels and threatening to destroy the nation’s pristine coastline – the country’s No 1 tourist attraction. Some of the archipelago’s low-lying islands could be fully submerged if the rise continues,” reported the National.

                              

4. Rhossili, Wales
     


Rhossili, a world-famous five-mile sweeping bay located on the tip of the Gower peninsula in southwest Wales, is in danger because of erosion caused by global warming and climate change.

5. Railay, Thailand
                                 

“I genuinely fear for Railay,” writes travel blogger Adventurous Kate. ”I’m afraid that it will become the next Koh Phi Phi, the entire island smelling like sewage because the infrastructure can’t handle the number of visitors.”
 6. Goa, India           
                    



“People around the world picture Goa as the ultimate beach destination and what adds to the charm is the lush green environs of the state. But locals and conservationists fear that iron ore mining companies in India are not only spoiling the natural beauty of the region, but threatening the lives of many wild animals stricken out of their forest homes,” reports IndiasEndangered.com.

7. Koh Rong Island, Cambodia



“Koh Rong Island is an inexpensive, unspoiled island getaway with turquoise-green waters, miles of powder-white beaches, endless palm trees, untouched fishing villages and only a handful of beachfront bungalows,” reports BBC Travel. But don’t wait too long if you want to see it that way. “In 2006, Kithr Meng, a Cambodian tycoon, purchased a 99-year lease on the island from the Cambodian government. His 20-year plan includes building an airport for small aircrafts, a marina, a golf course, casinos and several five-star resorts.”

 3D Holographic Projection Technology

This is a new HD Projection Technology in which a person is captured in 3D aspects with a special HD Camera On a specially built Stage and Projected “As Is “at various Distant Locations “At –A –Time”. Viewers at the other end will feel the presence of REAL Person in front of them and also interact with the projected ‘Virtual” person, without wearing any kind of 3D glasses, as they interact with ‘Actual Person’.


How it works

Holography is a technique that

enables a light field, which is 
generally the product of a light source scattered off objects, to be recorded and later reconstructed when the Original light field is no longer present, due to the absence of the original objects. Holography can be thought of as somewhat similar to sound recording, whereby a Sound field 
created by vibrating matter like musical instruments or vocal cords, is Encoded in such a way that it can be reproduced later, without the presence of the Original vibrating matter. A clever reimagining of the Pepper’s Ghost technique lets your magic happen. It starts with the patented foil, completely invisible to the naked eye. Rig it at 45°across the stage and then bounce content off a projector screen. This is then reflected upwards, reflects off the foil and gives the impression of a real 3D

Volumetric image on stage.

The holodeck was a giant, holographic projection room that allowed the crew to touch and interact with projections as if they were in a big video game. Scientists today are developing a new communications technology that will allow you and your friends to interact inside a simulated environment even if you are thousands of miles apart. ­
Most of the basic components for this network are already in place to allow the development of tele-immersion. Tele-immersion is the scientific community's answer to the holodeck.

By combining cameras and Internet telephony, videoconferencing has allowed the real-time exchange of more information than ever without physically bringing each person into one central room. Tele-immersion takes videoconferencing to the next level. It will create a central, simulated environment that will allow everyone to come together in one virtual room, and no one will have to leave their physical location to do so.
A mobile phone used to be a simple device for texting and calling. Then it became a smartphone boasting of Internet and camera functionalities. Now, the smartphone can be converted into a microscope through an attachable lens that can help magnify the object. One might wonder what the future would be like with a smartphone capable of projecting 3D holograms floating into thin air.

              Einstein's Theory of Relativity


Albert Einstein's theory of relativity is of two separate theories- Special Theory of Relativity in 1905, it says that the speed of light in vacuum was independent to the motion of all observers and his General Theory of Relativity in 1915 He says that massive objects cause a distortion in space-time,which is felt as gravity

The gravity

Force of attraction between two object is known as gravity  Even as the center of the Earth is pulling you toward it mass and weight are different concepts mass it is the amount of matter contained in a give body, and it does not vary with the change of its state & weight is the amount of pull, which the earth exerts upon a given body.since the pull varies with the distance of the body from the center of the earth,therefore weight of the body will also vary with its position on the earth’s surfays(say latitude and elevation)Yet Newton's laws assume that gravity is an innate force of an object that can act over a distance.
Scientists have tested this theory through experimentation - proving, for example, that an atomic clock ticks more slowly when traveling at a high speed than it does when it is not moving. The essence of Einstein's paper was that both space and time are relative (rather than absolute), which was said to hold true in a special case, the absence of a gravitational field. Relativity was a stunning concept at the time; scientists all over the world debated the veracity of Einstein's famous equation, E=mc2, which implied that matter and energy were equivalent and, more specifically, that a single particle of matter could be converted into a huge quantity of energy. However, since the special theory of relativity only held true in the absence of a gravitational field, Einstein strove for 10 more years to work gravity into his equations and discover how relativity might work generally as well.

 In his theory of special relativity, determined that the speed of light within a vacuum is the same no matter the speed at which an observer travels. As a result, he found that space and time were interwoven into a single continuum known as space-time. Events that occur at the same time for one observer could occur at different times for another.
As he worked out the equations for his general theory of relativity, Einstein realized that massive objects caused a distortion in space-time. Imagine setting a large body in the center of a trampoline. The body would press down into the fabric, causing it to dimple. A marble rolled around the edge would spiral inward toward the body, pulled in much the same way that the gravity of a planet pulls at rocks in space.

Experiment

Although instruments can neither see nor measure space-time, several of the phenomena predicted by its warping have been confirmed.
Gravitational lensing: Light around a massive object, such as a black hole, is bent, causing it to act as a lens for the things that lay behind it. Astronomers routinely use this method to study stars and galaxies behind massive objects.
Einstein's Cross, a quasar in the Pegasus constellation, is an excellent example of gravitational lensing. The quasar is about 8 billion light-years from Earth, and sits behind a galaxy that is 400 million light-years away. Four images of the quasar appear around the galaxy because the intense gravity of the galaxy bends the light coming from the quasar.
Changes in the orbit of Mercury: The orbit of Mercury is shifting very gradually over time, due to the curvature of space-time around the massive sun. In a few billion years, it could even collide with the Earth.
Frame-dragging of space-time around rotating bodies: The spin of a heavy object, such as Earth, should twist and distort the space-time around it. In 2004, NASA launched the Gravity Probe B. The precisely calibrated satellite caused the axes of gyroscopes inside to drift very slightly over time, a result that coincided with Einstein's theory.
Gravitational redshift: The electromagnetic radiation of an object is stretched out slightly inside a gravitational field. Think of the sound waves that emanate from a siren on an emergency vehicle; as the vehicle moves toward an observer, sound waves are compressed, but as it moves away, they are stretched out, or redshifted. Known as the Doppler Effect, the same phenomena occurs with waves of light at all frequencies. In 1959, two physicists, Robert Pound and Glen Rebka, shot gamma rays of radioactive iron up the side of a tower at Harvard University and found them to be minutely less than their natural frequency due to distortions caused by gravity.
Gravitational waves: Violent events, such as the collision of two black holes, are thought to be able to create ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory is presently searching for the first signs of these tell-tale indicators.
The electromagnetic field can have waves in it that carry energy and that we call light. Likewise, the gravitational field can have waves that carry energy and are called gravitational waves. These may be thought of as ripples in the curvature of spacetime that travel at the speed of light.
Just as accelerating charges can emit electromagnetic waves, accelerating masses can emit gravitational waves. However gravitational waves are difficult to detect because they are very weak and no conclusive evidence has yet been reported for their direct observation. They have been observed indirectly in the binary pulsar. Because the arrival time of pulses from the pulsar can be measured very precisely, it can be determined that the period of the binary systems gradually decreasing. It is found that the rate of period change (about
75 millionths of a second each year) is what would be expected for energy being lost to gravitational radiation, as predicted by the Theory of General Relativity.
For the final thirty years of his life, Einstein attempted to find a unified field theory , in which the properties of all matter and energy could be expressed in a single equation. His search was confounded by quantum theory 's uncertainty principle , which stated that the movement of a single particle could never be 
accurately measured, because speed and position could not be simultaneously assessed with any degree of assurance. An USSR stamp dedicated to albert Einstein for his theory of relativity

Healthier lifestyle could prevent Alzheimer's

Regular Physical exercise are
more essential for maintaining good blood flow to the brain as well as to encourage new brain cells. It also can significantly reduce the risk of heart attack, stroke and diabetes, and thereby protect against those risk Factors for Alzheimer’s and other dementia's.http://articles.economictimes.indiatimes.com/images/pixel.gif
Growing evidence shows that physical exercise does not have to be strenuous or even require a major time commitment.
It is most effective when done regularly, and in combination with a brain-healthy diet, adding vegetable’s in your food mental activity and social interaction. 
Aerobic exercise improves oxygen consumption, which benefits brain function; aerobic fitness has been found to reduce brain cell loss in elderly subjects. Walking, bicycling, gardening, tai chi, yoga and other activities of about 30 minutes daily get the body moving and the heart pumping.
Physical activities that also involve mental activity meditation, practicing mudras, plotting your route, observing traffic signals, making choices – provide additional value for brain health. And doing these activities with a companion offers the added benefit of social interaction.by making a few simple changes to their lifestyle, such as exercising more and quitting smoking, a new research suggests.
A third of Alzheimer's disease cases worldwide can be attributed to risk factors that can be potentially modified, such as lack of education and physical inactivity, researchers said.
http://articles.economictimes.indiatimes.com/images/pixel.gifCurrent estimates suggest that by 2050, more than 106 million people will be living with Alzheimer's disease, a huge increase on the 30 million people affected by the disease in 2010, researchers said.
Alzheimer's disease is caused by a complex interplay of genetic and lifestyle factors. Amongst the greatest lifestyle factors are lack of exercise, smoking, poor educational attainment and depression, all of which can be targeted to reduce the risk.practicing pranayama could be help much to over come this disease 
A study published in 2011 suggested that as many as one in two cases of Alzheimer's could potentially be prevented by modifying lifestyle factors. However, this study treated the risk factors as being independent of one another. The researchers estimate that by reducing the relative risk from each of these risk factors by 10 per cent, it will be possible to reduce the prevalence of Alzheimer's in 2050 by 8.5 per cent, preventing 9 million cases." Alzheimer's disease is placing an ever increasing burden on health services worldwide as well as on both patients and their careers.
Our hope is that these estimates will help public health professionals health policy makers design effective strategies to prevent and manage this disease,"

India invests far less than China, US & South Korea  (In science)

© civil society

MUMBAI: A report by a thinktank shows that India's investment in science has lagged behind that of neighbouring China, the US and South Korea, resulting in these countries staying ahead when it comes to research.
While India invested 0.88 per cent of its GDP in science research, the US invested 7-8 per cent, and South Korea 3-4 per cent.

Sudheendra Kulkarni said the "tight equation between a degree 

certificate and education has created several distortions, both in society and in the system of education itself
"Memorization of facts and formulae has triumphed over mastery
 of concepts, independent and creative thinking, integrative thinking that connects understanding of different subjects, and ability to apply that understanding to solve practical problems of society.". "Theory is prioritized over application and time constraints do not allow teachers to explore all concepts, in depth. As a consequence, students are frequently exposed to many concepts but fail to understand them in depth and explore their application. India is facing two kinds of disconnect: a formal science education pedagogy in colleges that is too theory-based and is disconnected from the practical world; and a large workforce in the informal sector of the economy whose practice is disconnected from
science education.Despite a large tertiary student population, India
 has not been able to increase the number of PhDs in science and 
engineering significantly (from 54 per 10 million in 1983 to 70 in
( 2004). China, which lagged India until a decade ago, now has 174 
science and engineering PhDs per 10 million.
India must invest more in science as its future is linked with it, and the country would change for the better if the government and the private sector increased spending on science education, leading scientist CNR Rao said Sunday. 
Rao, who is chairman of the Scientific Advisory Council to the Prime Minister, named for India's highest civil honour, the Bharat Ratna, for his contribution to the field of science. 
"India's future is linked with science. More investments will enable the youth to look at science as an important area of work for a great future. Only countries which advanced scientifically made progress, while those who neglected it are not known," Rao told reporters a day after he was conferred the country's highest civilian award. 
"It (support) is there, but not enough. We have to improve much more. If India invests in science over the next 10-20 years as much as China and South Korea do, we would be able to make up the lost time and catch up with them. We should have long-term investments in science and plan in advance," Rao said at his home-office located in the green campus of the premier Indian Institute of Science (IISc) in the city centre. 
"China and South Korea are doing very well in science because their investment is very high. They want to beat America after already beating Japan. South Korea is ahead of Japan in technology and innovation. I think we should become like that. Invest more in education and science to secure the future of India," Rao noted. 
Admitting that the government had not invested enough in basic education and basic science, Rao said if India has to race with China and South Korea in Asia, investment in both (education and science) should go up to six percent of the GDP (gross domestic product) annually. 
"As I said, India's future is tied up with the amount of investment the government would make in the coming years, as the contribution of the private sector was only around two percent of the GDP in education and science. We have to double our investment in science to two-three percent from 1-1.5 percent of the GDP," Rao said. 

Recalling that in his advisory capacity, he had done his best to further the growth of science and technology, Rao agreed that a lot more needs to be done in capacity building to meet the growing needs of over 1.2 billion people in the country. 
"In the last 8-10 years, India has done a lot of good things in science. Five new institutes of science have been set up in Bhopal, Chandigarh, Kolkata, Pune and
On technology overtaking science, Rao said unlike in the olden days, technology was developing faster than modern science and the time gap between research and innovation has shortened, especially in nanotechnology where research was turning into technology in a year.

Google seen best placed for growth as it 
transitions to mobile

Google Inc is the best placed of any company to benefit from the shift to mobile, increased local advertising and wearable’s, analysts said after the search giant posted its 18th straight quarter of 20 per cent-plus revenue growth.
At least seven brokerages raised their target price on the stock on Friday by as much as $75, to a high of $700.
http://articles.economictimes.indiatimes.com/images/pixel.gif
Google shares were set to open about 4 per cent higher at just over $600.
The company, which is also set to benefit from the so-called "internet of things", said on Thursday that second-quarter revenue rose 22 per cent to $15.96 billion, beating the average analyst estimate of $15.61 billion.
Growth was driven by the company's core search business, YouTube and product-listing ads, which combined to drive three times as much mobile traffic for merchants compared with last year, Jefferies analysts wrote in a note.
Brokerage Jefferies maintained its "buy" rating and $700 price target on the stock.
Of the 46 analysts covering Google, 36 have a "buy" or a higher rating on the stock and 10 have a "hold". There are no "sell" ratings, according to Star Mine data.
Google earns most of its revenue from advt.
The number of "paid clicks" by consumers on ads serviced by Google increased 25 per cent year-on-year in the quarter.
However, the average price of the ads declined 6 per cent as ad rates on mobile phones are typically cheaper than traditional online ads because of their smaller screens.
"Google is successfully transitioning its business from PC to mobile, and is arguably in a more favourable position in mobile than it was in PC, which should eventually be reflected in a higher multiple," Deutsche Bank analyst Ross Sandler wrote in a client note.
Google also owns Android, the world's most-used mobile software, and YouTube, the most popular video-streaming service.
Other online companies such as Facebook Inc. and Twitter Inc. are also revamping their advertising businesses to take advantage of the shift to mobile devices.
But Google has established unusually deep competitive "moats" around its business through scale, aggressive product innovation and substantial investment, RBC Capital Markets analysts wrote in a research note.
Google's capital investment budget has topped $17 billion over the past five years, and the company has spent about $13 billion on research, according to analysts.
The company is also spending big to push into new markets with innovations such as wearable computers, ultra-high-speed internet access and home automation - the "internet of things."
Google shares were trading at $604.33 before the bell, after closing at $580.82 on Thursday.
Up to Thursday's close, the stock had risen 26 per cent in the past year. The stock hit an adjusted life high of $615.03 in February.

Malaysian airliner downed in Ukraine war zone, 295 dead
      Reuters | Jul 18, 2014, 12.45 AM IST
   A Malaysian airliner was brought down in eastern Ukraine on Thursday, killing all 295 people aboard and sharply raising the stakes in a conflict between Kiev and pro-Moscow rebels that has set Russia and the West at daggers drawn.
© article.wn
As the United States said the Malaysia Airlines Boeing 777 from Amsterdam to Kuala Lumpur was "blown out of the sky", probably by a ground-launched missile, Ukraine and Russia traded accusations of blame, cranking up global pressure for a way out of a bloody local conflict that risks fueling a new Cold War.
Ukraine accused pro-Moscow militants, aided by Russian military intelligence officers, of firing a long-range, Soviet-era SA-11 ground-to-air missile. Leaders of the rebel Donetsk People's Republic denied any involvement and said a Ukrainian air force jet had brought down the intercontinental flight.
But separatists have said that they took control of such a missile system last month and had used it to shoot down a Ukrainian military transport plane that was destroyed on Monday.
The scale of the disaster, which left scores of unsuspecting foreigners, adults and children, strewn lifeless across the muddy Ukrainian steppe, could prove a turning point for international pressure to resolve the crisis. It has killed hundreds in since protests toppled the Moscow-backed president in Kiev in February and Russia annexed the Crimea a month later.
The United Nations Security Council plans an emergency meeting on Ukraine on Friday, diplomats said. U.N. Secretary-General Ban Ki-moon urged a full international investigation.
Reuters journalists saw burning and charred wreckage bearing the red and blue Malaysia insignia and dozens of bodies strewn in fields near the village of Hrabove, 40 km (25 miles) from the Russian border near the rebel-held regional capital of Donetsk.
More than half of the dead, 154 people, were Dutch. Another 27 were Australian and 23 Malaysian.

The Ukrainian government, condemning an act of "terrorism", released recordings it said were of Russian intelligence officers discussing the shooting down of a civilian airliner by rebels who may have mistaken it for a Ukrainian military plane.
Russian President Vladimir Putin pinned the blamed on Kiev for renewing its offensive against the rebels two weeks ago after a ceasefire failed to hold. The Kremlin leader called it a "tragedy" but did not say who brought the Boeing down.
U.S. Vice President Joe Biden said the jet was "blown out of the sky" and a U.S. official said that, while its origin was unclear, a surface-to-air missile was probably responsible.
After the downing of several Ukrainian military aircraft in the area in recent months, including two this week, Kiev had accused Russian forces of playing a direct role. International air lanes had remained open, though only above 32,000 feet. The Malaysia plane was flying 1,000 feet higher, officials said.
U.S. President Barack Obama said it was unclear whether Americans were aboard. A Ukrainian official said there were 23.
As word came in of what Ukraine's Western-backed president called a "terrorist attack", Obama was on the phone with Putin, discussing a new round of economic sanctions that Washington and its EU partners imposed to try to force Putin to do more to curb the revolt against the Western-backed government in Kiev.
They noted the early reports during their telephone call, the White House said, adding that Obama warned of further sanctions if Moscow did not change course in Ukraine.

WRECKAGE, BODIES

Malaysia Airlines said air traffic controllers lost contact with flight MH-17 in the afternoon as it flew over eastern Ukraine towards the Russian border, bound for Asia with 280 passengers and 15 crew aboard. Flight tracking data indicated it was at its cruising altitude of 33,000 feet when it disappeared.
That would be beyond the range of smaller rockets used by the rebels to bring down helicopters and other low-flying Ukrainian military aircraft - but not of the SA-11 system which a Ukrainian official accused Russia of supplying to the rebels.
Separatists have been quoted in Russian media saying they had acquired one. One group was quoted as saying that it used an SA-11 on Monday to bring down an Antonov An-26 turboprop plane - a loss that the Ukrainian forces had confirmed this week along with the downing of a Sukhoi Su-25 fighter on Wednesday.
"I was working in the field on my tractor when I heard the sound of a plane and then a bang," one local man at told Reuters at Hrabove, known in Russian as Grabovo. "Then I saw the plane hit the ground and break in two. There was thick black smoke."

An emergency worker said at least 100 bodies had been found so far and that debris was spread over 15 km (9 miles). People were scouring the area for the black box flight recorders and separatists were later quoted as saying they had found one.
Kiev complained that separatists who are the main force in the area prevented Ukrainian officials from reaching the site.


Malaysian Prime Minister Najib Razak demanded swift justice for those responsible and said the crash site must not be interfered with before international experts had access.
"MH-17 is not an incident or catastrophe, it is a terrorist attack," Ukrainian President Petro Poroshenko tweeted. He has stepped up his military campaign against the rebels since a ceasefire late last month failed to produce any negotiations.
One rebel leader, the self-styled prime minister in Donetsk, said they could agree a truce of two or three days to help with investigation of the incident.
Russia, which Western powers accuse of trying to destabilise Ukraine to maintain influence over its old Soviet empire, has accused Kiev's leaders of mounting a fascist coup. It says it is holding troops in readiness to protect Russian-speakers in the east - the same rationale it used for taking over Crimea.
Ukrainian Interior Ministry official Anton Gerashchenko said on Facebook: "Just now, over Torez, terrorists using a Buk anti-aircraft system kindly given to them by Putin have shot down a civilian airliner flying from Amsterdam to Kuala Lumpur."
The Buk - which means beech tree in Russia - is a 1970s vintage, truck-mounted, radar-guided missile system, codenamed SA-11 Gadfly by Cold War NATO adversaries. It fires a 5.7-metre (19-foot), 55-kg (110-lb) missile for up to 28 km (18 miles).
"There is no limit to the cynicism of Putin and his terrorists!" Gerashchenko wrote on the social media site. "Europe, USA, Canada, the civilised world, open your eyes! Help us in any way you can! This is a war of good against evil!"
He also published a photograph he said showed a Buk launcher in the centre of the town of Torez on Thursday. It was not possible to verify the image. On June 29, Russia's Itar-Tass news agency quoted a separatist spokesman in Donetsk as saying they had taken control of a Buk air-defence system.

REBEL ACCUSATION

The military commander of the rebels, a Russian named Igor Strelkov, had written on his social media page at 1337 GMT, that his forces had brought down an Antonov An-26 in the same area. It is a turboprop transport plane of a type used by Ukraine's forces. There was no comment on that from Ukrainian officials.
Flight MH-17 could have been in that area around that time, just over three hours after it took off from Schipol airport.
Several Ukrainian planes and helicopters have been shot down in four months of fighting in the region. Ukraine had said an An-26 was shot down on Monday and one of its Sukhoi Su-25 fighters was downed on Wednesday by an air-to-air missile - Kiev's strongest accusation yet of direct Russian involvement, since the rebels do not appear to have access to aircraft.
Moscow has denied its forces are involved in any way.
The loss of MH-17 is the second disaster for Malaysia Airlines this year, following the mysterious loss of flight MH-370. It disappeared in March with 239 passengers and crew on board on its way from Kuala Lumpur to Beijing.
In 2001, Ukraine admitted its military was probably responsible for shooting down a Russian airliner that crashed into the Black Sea, killing all 78 people on board. A senior Ukrainian official said it had most likely been downed by an accidental hit from an S-200 rocket fired during exercises.
In 1983, a Soviet jet fighter shot down a South Korean airliner after it veered off course into Russian air space and failed to respond to attempts to make contact. All 269 passengers and crew were killed.
In 1988, the U.S. warship Vincennes shot down an Iranian airliner over the Gulf, killing all 290 passengers and crew, in what the United States said was an accident after crew mistook the plane for a fighter. Tehran called it a deliberate attack.
