When the foam problem is solved, there still might be a question of
bird strikes.

If a 1.5-lb piece of foam going 500-mph does this kind of damage, what
would a 3-lb to 7-lb bird struck at 200-mph or 300-mph do? KSC is a
wildlife refuge. They've never hit one yet, but there's always a first
time.


At what altitude does the shuttle reach these speeds?

At what maximum altitude do most birds fly?

And, falling debris is conscious of nothing. I suspect birds will
actively tend to avoid the, ah, modest disturbance that a shuttle launch
generates.


If the shuttle is supersonic, they may not hear it coming.
Even if it isn't, they might not be able to manoever enough to generate a
miss, as it's not something they train for

A quick google for "highest flying bird" reveals that a vulture hit a plane
at 37000 feet.
Call this 12Km.
The shuttle goes supersonic at 40 seconds in, at around 7Km.

I think the altitude at which the shuttle outpaces the noise of ignition
is around 10-12Km, so it's even concievable that the bird might not
even hear it.
