Its worth making to show to any truthers that still have a modicum of sense remaining, but there's no way I'm sitting through more than a few minutes of this, particularly not after having seen "Loose Change".
Unless you're planning to discuss 9/11 with Truthers, you don't need to watch this for the same reason a person who's not sick doesn't need to take medicine. So it's not like you have to watch and enjoy it, it's not there for people who've caught a case of the dumbshits.
The arguments are just as sophomoric as the original video. Its like watching two idiots mind wrestle in a bar. Also: Unbearable "Microsoft Flight Simulator" as if that was supposed to prove something.
