Evenin'
When I was doing my initial ATCO training, I learnt that the highest recorded bird strike was a vulture at 32,000 feet! (From memory. It was more than Fl300 anyway!) At the time I was mighty suspicious of this: How could it survive up there? How did it get up there? If this is the case then I'm impressed but surely there must be some mistake in the figures here??
Edit: Quick Wiki search gave the answer here
