We were taking delivery of a new jet years ago and our POI (FAA inspector)was getting typed in it. In fact, his check ride was the actual first flight in the US. Anyway on short final to 12L, they smacked a goose on the left leading edge right near the root. They got it on the ground and taxied it to the hangar where we were all waiting to see the new bird.(Literally)As he parked we could see something was wrong, but it wasnt until we got closer we saw what happened. The entire leading edge was ruined. Avian remains all over the side of the plane, and a very sheepish FAA driver. Twarnt his fault, though. The wing had to be replaced grounding our brand new bird before it had even been weighed. Had the goose hit the windshield, there would have been a much different result..
People don't realize how much damage they do. That's why I posted some of those pictures. It's an enormous hazard.
I've heard of several deer strikes too - which are deadly. I fly into several fields where we need to do a low pass or two to clear the runway.
