Hi, Mark, That "high-pitched scream" you hear as the one kilometer impactor drops on the planet is not coming from the impactor -- it's coming from us! My research indicates about half the human population emits a "high-pitched scream" while the other half creates a strong low-frequency rumble that sounds alot like "Oh, Sh----!"

Hi folks, On another forum someone posted about a recent TV programme he'd watched about NEOs. At the end the guest astronomer said something to the effect that "the first we know about an incoming impactor could be the high-pitched scream as it speeds through the atmosphere." It got me wondering; a sizeable body would be travelling at cosmic (ie very supersonic) velocity right through to impact, and therefore the "scream" should trail behind the object - in other words, we wouldn't even get that much warning. Was the speaker using poetic license or would there be any kind of fore-shock?
