Not sure if this is the right forum for it, but heres my 2 cents. A lot of talk about an engine falling off is being thought as the cause of the crash. I think it was terrorist. I can think of 2 cases where commerical or large military aircraft have lost engines and remained airworthy. One happened in the gulf war. I think a KC135 was landing behind a 747 and the turbulence tore one of the engines off the KC135. It landed safely. Another case happened just a few years ago. A b52 lost an engine 'pod' and it landed safely. Of course there have also been incidents where they didnt land so safely. A large commercial jet had an engine actually fall off while it was still over the runway and it subsequently stalled and crashed. And I assume your familiar with the Souix City crash. It was a remarkable feat of flying.
