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.

White House Down (2013)
Ending / spoiler
Directed by: Roland Emmerich
Starring: Channing Tatum, James Woods, Jamie Foxx, Richard Jenkins, Maggie Gyllenhaal
At the end of the film Raphelson and Finnerty fly to the White House on Marine One, and they meet up with Cale. Cale proceeds to tell Raphelson that President Sawyer is dead, so Raphelson orders troops back into the Demilitarized zone, which is a violation of the peace treaty. Raphelson confronted over the fact that it was him who gave Walker the launch codes and tried to kill the President and the air strike would have destroyed all the evidence that proved he was involved in the attack. President Sawyer then emerges from the rubble and orders Raphelson arrested for treason for the attempted coup.
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).
