For those of you who can't get enough aeroporn, the new show on National Geographic (honestly, I didn't even know we got this channel) on Air Force One (and also Marine One) is pretty cool. You get some good inside views of the plane as well as some good insight on the security on the ground.
Also cool was a description on the use of the two planes, how they travel together, etc.
Worth having your TIVO pick it up next time it's on.
