Factual error: The attacking helicopters get a "missile lock" warning on two occasions from the Javelins, despite Javelins being infra-red guided, meaning there's no active signal for the helicopters to detect.

More trivia for White House Down
Question: At least a couple of times the grenades make a clear "clockwork" noise before going off, which I don't recall happening in many other films. Do any grenades actually make a noise like that? Or is it actually accurate, and silent grenades are the inaccurate "movie" versions?
Chosen answer: Grenades generally do not make any sound until they detonate. When you release the spoon (lever) as you throw it, it can make a "ping" sound as its separates from the grenade. No clockwork noises. (I'm ex Army).
