Based on what?
Based on how the aircraft was destroyed. To blame the fuel tank sensor was a rediculous ploy. That sensor has been used in thousands of aircraft prior to and after the incident with no problems what so ever. The eye witness accouts, the photo's, the aircraft flight path and the damage done are all indicative of a shoot down. This may have been something else, but it was not the fuel sensor and it does match a shoot down scenario. Reports also indicate that there was some Navy testing of an anti-aircraft system in the area that night (only reports and no proof on this but it makes me wonder).
What do you have to challenge this theory? I would be interested in hearing.
