Were the hijackers really devout muslims, or someone posing as muslim>? Even more outrageous, is it possible that the captains Dahl and Homer thought they were participating in an anti-hijacking DRILL, therefore thought that the cabin intrusion was part of game, for which they were rewarded handsomely? Just a speculation, based on the fact that Pilot Homer had previously flown Dick Cheney, and Pilot Jason Dahl had reportedly just lavished a new car and a new piano on his family. (where did the money come from?)
