Why is this crash still widely believed to be an act of suicide, when the only evidence that supports it is the fact the pilot disengaged the autopilot and was navigating the plane downwards... what made it even more fishy and dubious, is this quote I found by the NTSB(NATIONAL TRANSPORTATION SAFETY BOARD) while summing up the investigation: "Investigators cannot rule out the possibility that the RFO may have taken emergency action to avoid a collision with an unknown object. Although plausible, this theory cannot be tested because the United States has refused to release certain radar calibration and test data that are necessary to evaluate various unidentified radar returns in the vicinity of Flight 990." WHY WOULD USA NOT RELEASE THIS INFO? It seems that in a crash like this where so many innocent lives were lost, it would be counter productive and to hide information like that from the NTSB.. The families deserve answers, and by our govt not releasing this info. , it makes it all the more apparent that it WAS NOT A CONTROLLED SUICIDE FLIGHT BY THE PILOT!! I know this should be in the air travel section... but I just cold not get an aswer... and I figured since it possibly involves coverups by the US army possibly accidently shooting it down, or conducting tests with UFO's... hahaha i know it was not a damned UFO... the point is that WE DONT KNOW WHAT HAPPENED... BC USA REFUSES TO RELEASE ALL INFO! if someone can tell me WHY USA DIDNT RELEASE INFO, they get automatic 10 points...
