my reasons for not believing the official story are,
1, it seems ludicrous that a passport survived the fire that cremated the hijacker and destroyed the flight recorders in fireproof cases.
2, if a passport did not have to be shown to board an internal flight, would a terrorist on a suicide mission have bothered carrying one anyway?
(unless they needed it to get into paradise and meet their 72 virgins)
http://rationalwiki.org/wiki/Argument_from_incredulity
The argument from incredulity is a logical fallacy that essentially relies on a lack of imagination in the audience.
The general form of the argument is as follows.
- Major premise: One can't imagine (or has not imagined) how P could be so.
- Minor premise (unstated): If P were so, one could imagine (or would have imagined) how.
- Conclusion: Not-P.
