My father had a major Goose strike once. He was flying his plane late at night and all of a sudden multiple BANGS. His windshield was covered in guts and he couldn’t see properly, his controls were not acting right etc. Luckily he was close(ish) to an airport where he could make an emergency landing. He pulled up to a fuel depot and the guys came out to meet him to see if he was ok. He got out and the fuel guy said something like “Holy $&@# you were just flying that?” Most of the rudder was gone, the prop was bent to hell, there were 2 massive dents in the wings. He flew though en entire flock of geese.
