I thought about it when I saw the advertisement, but decided against it. The ONLY thing known for sure about that flight is that it was hijacked, calls were made from it to family members, the callers apparently managed to force a confrontation with the terrorist scum hijackers, and the plane crashed.
Anything beyond that is pure speculation, and I'm not too keen yet on watching dramatizations of events about September 11th yet that isn't all based on fact.
