Dunno about prop strikes, Never went near em. I did have a habit of carrying a 12" GS in my pocket whenever I did an intake inspection, the bloke that taught me the habit reckoned if someone did manage to start the damn jet up it would buy him enough time to get it jammed in the LP fan and back out the intake, most sooties are too fat to turn round in the intake, also there is the small matter of the strake and if you weren't extremely careful you'd be lighter on exit by two test tickles
.
If it's broken its because you let a pilot touch it!!!
