[The theory that MH370 may have been accidentally shot down in US-led military exercises and is now being covered up to prevent a Lockerbie-style retaliation is now being discussed widely in the media. Here is an excerpt from an article by John Chuckman on the OpEdNews website:]
A second mystery around the disappearance of Flight MH370 has largely gone unnoticed: why hasn't the United States been in the forefront of providing information about it? The implications of this question are massive.
America has a fleet of the most sophisticated spy satellites, called "keyhole" satellites, covering the earth's surface daily with imaging systems comparable to those of the Hubble Space Telescope, but instead of data from any of these, we read of data from China and France. One can understand that the CIA does not want others to understand fully the capabilities of its satellites, but surely the lives of more than two hundred people are cause for some information, however indirectly supplied.
Then again, the American military has some of most sophisticated radars on earth, and there is, without a doubt, an installation of the highest capability at the secret base on Diego Garcia in the Indian Ocean. How could there not be? But we have read of no data from them, only from others less capable of telling us what happened.
Could it be that the United States shot down Flight MH370, either accidentally or deliberately, and now wants to keep it secret? (...)
There would be nothing unprecedented in such an act: on at least 3 occasions, regrettably, America's military has shot down civilian airliners, only admitting eventually to the one they could not hide. They are also indirectly responsible for a fourth.
Iran Air Flight 655 was stupidly shot down in 1988 by the USS Vincennes in Iranian waters during the Iraq-Iran War, not only killing 290 people including 66 children, but there was a long period afterwards in which the US admitted no wrong-doing, offered no apology, and no compensation to its victims (only 8 years later was a quiet settlement made).
It was a quite vicious set of circumstances and the injustice of it led unquestionably to the motive for bombing Pan Am Flight 103, killing 259 people and 11 on the ground, later the same year by people still unknown.
