I’ve never had a squirrel strike, but I did have two bird strikes when flying helicopters. With both of them I got pretty lucky, … the bird not so much…
On one I just grazed the bird with the rotor-tip which ripped all the feathers off the bird and it pretty much fell to its death featherless. It was kinda heartbreaking to watch. On the other one, the bird hit the skids which is pretty much the best place for a bird to hit a helicopter. Again, for the helicopter and everyone onboard, and not for the bird.
I did, however, have an owl eat a squirrel it caught on top of the rotorhead one night. In the morning there were squirrel pieces all over the top of the helicopter. And the owl had made such a big dookie, it ran down the entire side of the aircraft, and there was enough left by the time it reached the bottom, to drip on the ground, squirrel bones and all… gross.
We’re probably not going to make a strip out of that particular story though.
