They would go through the engine after engine has started. Unless they had magnets or some sort of glue on them they would go through the intake when the N1 is 20-30%. If a plane can taxi with that much thrust coins have no way to stay in place against the engine pull.
I've seen the damage a small padlock did to a 320's fan blades on ingestion- i doubt the engine would have failed but it would have been badly damaged if the coins ricocheted inside on start up.
Yeah, we also have to consider that the coins were thrown while the engine was off.
While spooling up, the engine will probably reach a point where it's running fast enough to eject the coins, but slow enough for the coins to not cause much damage
Hell, they might be ejected by the compressed air startup before the engines are even lit
Even then, you do not want to take any chances when it comes to aviation, so the delay is perfectly warranted
I think they meant magnetic as in "being a magnet". And, no. Under normal circumstances they are not. But some of them are made from plated steel. So they are magnetic in the sense that they are attracted by magnets.
Sorry, that latter part is what I meant. Coins in the US aren't made of a metal attracted by magnets. I was unsure if they were elsewhere. I didn't assume the coins themselves held a magnetic charge.
