Other mistake: After the sprinklers go off in the White House, none of the actors' clothes are wet. With the amount of water sprayed, all of them should have their clothes stuck to their bodies. (01:25:00)
Other mistake: Near the end, the sprinklers are turned off in the oval office, which should mean they are all turned off as they all came on together, but where the fist-fighting continues, the sprinklers are still on.
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.
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).
