Freaking jet engine! Apparently for "good luck" before takeoff lol http://www.newsweek.com/woman-throws-coins-plane-engine-good-luck-delaying-flight-five-hours-629509
Or to ensure that it isn't. 911 caller: "Send help! I accidentally shot my husband, and I think he's dead!" 911 operator: "Okay, I need you to remain calm. First, can you make sure he's actually dead?" 911 caller: "<BLAM> <BLAM> <BLAM> OK, what do I do now?"
Because the engine wasn't running, the coin would have probably been blown out the turbofan bypass on start-up without causing damage. However, it's not certain! So the inspection was absolutely needed. Passenger jet engines suck in small bits of hardware or gravel all the time. Usually, it hits the front blades, slides to the periphery, and goes through the bypass without wrecking the engine. Once in a while though, it ends in disaster, not just for the engine but for the plane and all on board. Jets that use gravel runways usually have gravel deflectors installed on the engines to minimize the intake of small stones. Cal
