Third, is there an official accident report on-line that concludes what happened on his fatal flight? In one of the links above, it mentions that the Mig-21 was going into the ocean at a high-rate of speed. To me that would indicate either a loss of consciousness (i.e. G-Loc, or incapacitation from a heart attack, aneurysm, etc.), spatial disorientation, or some kind of departure from controlled flight due to loss of aircraft control. Does anyone know what happened?
I hate to talk out of my rear end, but this is the account I've been told;
Mig-21's are equipped with a centerline fuel tank. The pilot handbook expressly states not to go supersonic with the centerline tank empty, as a structural failure can result, causing the aircraft to break up in flight.
In this case, the aircraft apparently exceeded the sound barrier with the centerline tank empty, suffered a structural failure, and broke up in flight. I have not heard any speculation as to why the aircraft went supersonic, only that it did.
Again, take that scuttlebutt for what it's worth. I've not seen the actual incident report. Perhaps some of the jet jockeys can shed some light on this, does anyone know of a "do not exceed the sound barrier with an empty fuel tank" restriction on other aircraft? Is this at least plausable?
