Visible crew/equipment: In a scene midway through the film where Glenn Close etc receive the fax from the plane, the tracks for the camera can be seen on the floor.

Air Force One (1997)
1 visible crew/equipment mistake - chronological order
Directed by: Wolfgang Petersen
Starring: Gary Oldman, Harrison Ford, Glenn Close
Factual error: The plastic explosive used on the cockpit door was C-4. When shot (as shown), C-4 does not explode; it requires the use of a detonator.
President James Marshall: I trusted you with my life!
Agent Gibbs: So will the next president!
Trivia: One of the secretaries tells the president she can send a fax to the White House, and he replies something like: "If this works, I'll make you Postmaster General". In the closing credits, she's credited as "Future Postmaster General".





Suggested correction: You can see him applying a detonator prior to him shooting it.
If he applied a blasting cap (detonator) he should have used it then. Just putting a detonator into C-4 doesn't all the sudden make it vulnerable to being shot, he would have to actually hit the blasting cap's wire, which is about 5mm thick and relatively short (and it would have to be one that's sensitive to gunfire). Not a very probable shot, even less so when he doesn't even look when he shoots.
