I see a lot of bugs that simply go through the rotor disk unharmed, but I've seen bug splatters all over airplane props...

I was talking to a guy a while ago about why bugs seem drawn to helicopters. His explanation was that the sound frequencies of the engine and the rotors attract them. Why, I don't remember...

When I used to fly slope combat a lot, I'd always try to chase the hawks, and the smaller birds always like to chase me. Just never was able to hit them.
