Well, I know that on the YF-22 program, one of the engine manufacturers
did in fact cut loose a few turbine blades during system test -- although,
in that case, it was unintentional. We also ran one of the aircraft into the
ground -- again, unintentionally.
As for the birds, there is an interesting test done here in Fort Worth. (At
least, we used to do it -- I haven't actually witnessed one of these tests lately).
To determine if the canopy will survive a bird strike, they actually take a bird
(presumably of mil-spec size and weight), load it into a cannon-type deveice, and
fire the bird at the canopy. By the way, it's not a good idea to use a _frozen_
bird for this test...
