I know this is coming late to the game...but here are a couple of
things...If you know the aircraft and Andrews Air Force Base, this is
NOT Air Force One.

Air Force 1 is never parked that close to any fence accessible from off
the base. Most likely this is a 747-100 or 747-200 that has been
painted like Air Force One for a movie or television program. The most
recent repaint I can think of was a 747-200 that was repainted and used
in a few films...including the movie Air Force 1 and season 5 of "24."

Also, if you look closely at the video, the aircraft only has one
communications antenna on the top of the fuselage. The real Boeing
VC-25A's (there are 3 if I remember correctly) that are used for
presidential travel have many sat and RF communication antennas on the
top of the aircraft:

There is also no lower entry hatch near the presidential seal and no
refueling "bump" on the nose.

Then there is also the disclaimer on the site and the complete lack of
any coverage in the news. It would be hard to keep something like this
secret.

Cheers.
