Re: It's time...
'My old man flew those things when getting shot at. He's got a picture of one he flew back with a pretty damn big hole in it.'
He was shot at in an R-22? If it was something like a Huey (Bell 205) then I'd have no problem believing that, they have big solid blades with something like the outer third containing a bronze lump to give the rotors plenty of inertia in case the engine failed. To spin this around the Bell has a 1100 horse power engine. The R-22 is basically built of tin foil and has a very light weight rotor system with virtually no inertia, because of this it's one of the few helicopters the FAA requires additional training for auto-rotations in. It has a mighty 124 hp to spin things around and you can't even start the engine connected to the transmission.
So you'd definitely notice a Phantom sized drone hitting the rotors, and it'd probably leave marks. The problem is you then have no idea what has happened to the internal structure, which is so reassuringly solid part of the pre-flight checks are to tap the blades with a coin to see if there's a change of noise to indicate de-lamination is taking place.
Disclaimer, I've flown the R-22 and the Bell 206 which shares its elder brothers robust rotor system.
