During this same time, there is some evidence that shortly after crossing the Malaysian Peninsula, Flight 370 was in trouble. The radar playback shows that the plane took three sharp turns: right, left, right at an altitude of 35,000 feet and at a speed of 473 knots - just before the radar readings instantly go from 35,000 feet to 0, with the plane still traveling at that speed for a few moments more, at 0 feet altitude before it vanishes from the screen. As of this writing, this plane remains missing, even though the sea is relatively shallow in the area where the lane went missing.
As for the other object described here, it disappears as well. There have been no reports about this object - or plane, or what have you; whether it was a commercial airliner, like the many others in flight during the final moments preceding the disappearance of Flight 370 - but the object in question certainly didn't behave like a commercial airliner.
Regardless of whether or not this mystery object had anything to do with the demise of of Flight 370 - what IS evident is that the radar readings shown in this clip captured signals from what for now, can only be termed a UFO.
