GUEST,Chief Chaos BS: UFOs in the news (342* d) RE: BS: UFOs in the news 03 Jun 08

I understand Doppler shift, and the speed of the shuttle was just a number pulled out of wherever. I just hadn't thought of the actions of light being relative to the actions of sound (with an object moving fater than the speed of sound). I guess if travel at faster than the speed of light were possible. An object would suddenly appear as it dropped below FTL. But would it be followed by a trail of it's image like the roar of a jet following seconds behind the jet travelling at Mach 2?
