Of course a less than satisying sound is the start sequence being energized by morons in the cockpit engaging the starter when you have your hands inside the fan on an engine. Turns out they were trying to get some airconditioning going on a hot day in MNL and hit the wrong switch. A couple of guys came rolling out of the inlet pretty quick
With your experiece and knowledge concerning turbofan and turbojet engines i doubt you would put your hands anywhere near N1 stage unless any source
of bleed air was unavailable. Anyway, from the moment that you hear the starter and to the fan starts sucking in big objects there's plenty of time to get out of the intake and
walk to a safe distance.
Dealing with aircraft engines on the line with anyone on the flightdeck, expect at least one moron flippin switches.
