This incident involved the Oklahoma Thunder NBA Basketball team and there seems to be a bit of a mystery as to the cause:

Some accounts I've read seemed to indicate that it happened very high - 30K feet. I'm curious - at what height do you pilots stop worrying about birds?
What are your theories as to what caused this?
Thanks!
