OM 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. -- http://inquisitor.i.am/ | | Ian Stirling. ---------------------------+-------------------------+-------------------------- 'Where subtlety fails, we must simply make do with cream pies' -- David Brin |
