There are definitely a ton of unanswered questions about that day -- there are a lot of theories, ranging from very plausible and reasonable (IMHO) to fairly unhinged and over-the-top. The problem is, anyone who questions the official version automatically gets characterized as a paranoid wacko.

(That's another conspiracy theory -- that the most wacko theories were put out there deliberately to discredit the people asking reasonable questions!)
