Ace Baker's no-planes episode is now up. It's pretty good, but not as good of a treatment of the issue as I'd expected. It's probably worth $2 though obviously only if you have an extra $2. He spends a fair amount of time of the lack of "wake vortex" at the WTC, which is an interesting point, but not exactly definitive (it's not clear one could form next to a building where a plane has supposedly crashed, nor is it clear that there is no evidence of it at the south tower). The stuff with Mete Sozen and his Purdue animation is funny, though nothing really surprising in terms of how bogus it was.
