I think the DC3 had 8mm glass windscreens. But it flew so slow, are you sure the goose didn't strike the DC3 and come in through the tail from behind?
Nope.....right through the right front windshield. Killed the Co-Pilot on a North Central (Wisconsin Central) DC-3. Don't ask me dates/times/places, as I don't know. Sometime in the early 50's probably as I heard about it when I first started out at their Base.
