its happened before to a northwest airlines flight in 2008, what was described as a minor maintenance issue (because it sounds better than structural failure) happen to flight 478 before it landed at tampa. Aren't nose cones normally the only bit of the aircraft shell not made of metal?
here's a photo
oh and just a note the highest flying bird ever recorded was a ruppells vulture at 36,100ft
