Which reminds me: There is speculation around about the reason for shutting off cell service while flying. The official reason is that it might interfere with airline navigation, which is complete hogwash. The real reason is obvious, to me anyway. The regulation came about after 9/11, and most likely is there so that people could not learn for themselves that cellular communication is impossible from moving aircraft.
Have a nice day, frightened nation! The TSA today will be fingering countless ball sacks in search of box cutters.
