Theres a lot of speculation about TWA Flight 800 so thats pretty interesting. I some how stumbled on CPAN one night and the guy that wrote TWA 800 Crash Cover Up Conspiracy was giving a talk. Listening to the commenters afterwards, all were either engineers, pilots, or former air force and seemed to be in agreement with the author. Theres a TWA Flight 800 documentary as well.
