Not a can strike, but I had a Mountain Dew can blade taped to a hole in my fuselage for a fly off...I had a Mountain Dew (maybe it was Sprite) strike to the rotor while in the perch. Should I have written that up?
The BASH report on that one was asinine. (Orientation? Fvck, we were on the line.)
Some guys will turn early to avoid a single. I think that if you do that, the bird thinks you're his buddy and will turn to join!
