Does anyone have a picture of the buses being driven on or off one of the Presidential transport planes? That would be great confirmation of this story.
I could be wrong, but believe the only AF aircraft large enough to transport the buses would be the C5. Was one of those used? If so, it would likely have been noticed by a lot of people. Those babies are truly massive...
FWIW...
