[On the theory that one or more 9/11 airliners had underbelly missile "pods."]

The pod theory is definitely among the most seemingly outlandish theories out there other than the "no plane" theory, and is likely to have you branded as a "conspiracy nut", but I can't honestly say I find it anywhere near impossible or even improbable. If it is indeed true, then it's smoking gun, irrefutable, solid evidence that the attacks consisted of far more than "Arab hijackers with box cutters".
