Cheif Chaos , your observation is very intuitive and full of excellent imagery of a jet's roar lagging behind yet physicists claim that the light from a speeding craft will stay below the speed of light to both the shuttle and a relative stationary observer.

Amos , I saw several turns by different debris/objects that all seem to have a small slice cut out of them. Notice how the camera makes them pulse with an optical illusion when they pan away.

Anyway the many ufo fakes on you tube are accented by a few very real phenomenon.
