If you haven't seen it, they take two new undelivered 747 800's that were ordered by a Russian airline out of storage to convert to the new Air Force One's.
One thing that struck me was the crew saying they were glad to be going over to a modern digital cockpit over steam driven instrumentation then showing the guy gutting the new aircrafts cockpit to militarise it by fitting completely new hardened wiring and displays to protect it from an EMP pulse in case of a nuclear war, A lot of the steam driven instruments that they were glad to change over from in the earlier aircraft wouldn't have been affected by an EMP. So much for technology advancement.
