I remember a story from Malaysia, where an old peasant woman, while in line boarding a plane from the tarmac, tossed some coins into a rotating jet engine “for good luck on the flight.”
I remember that too.
That was considered a common act of sabotage in the USAF.
We had “bull pens” to put in front of engines when running them for maintenance to keep people away. While running such an engine at full force I saw it pick up a pool of rain water on the ground and suck it into the engine.
ROFL!!
