IMO, the question is not as much on VMO or vastly exceeding it, but more on the fact that those 'crews' supposedly successfully adapted in no time from 100 knots on Cessna 172 to 500 knots on Boeing 767 to precisely hit their target, and so with no waste.
so what...? the goverment by itself captured the planes and let it land at area 51, then eliminated all passengers and the own kidnappers, removed the real planes and let intentionally crash rc controlled 767 in the wtc...?
that would be much better than the moon hoax conspirancy !
