OK, good points. However, that would require a LOT of assets being pumped through the dummy corporation over a long period of time--owning and operating an airplane ain't cheap, and people start wondering what the heck's going on when one AIN'T flying for a while, unless they park it out at Mojave Airport--and the Feds have been known to keep an eye on Mojave just because so many questionable activities, like parts theft, take place there.
The best terrorist plots have the advantages of the best military plans: speed, surprise, simplicity. 9/11 used all three.
all true but just wanted to pt. out that chartering/leasing a plane may be easier than stealing one.
