What if
It was a tomahawk
9 11.01 saw all manner of "exercises" that day.
What if said tomahawk was in the hold over that reserve airbase in NJ or wherever all three hijacked planes were reported to overfly
And then an F16 picked up dg for the missile and sent it where needed
That capability was being explored at that time
Navy E2C or something for the gibs
Stack em
Pack em
And send them on their way
Observers may think they're just in a hold
