Bob Lazar explains the "shape shifting ufo"
This "shape shifting" ufo was filmed by a passenger on an airliner. Of course its not shapeshifting is a disc UFO: what you see shifting is the envelope of the gravity field generated by the disc as it intesifies, just like Bob explained it 35 years before. The disc is always at the center of the V of the Y shape which in fact is a donnut 360 shape.
