Default Help please? Physics question.?

An airplane generates soundwaves. When it flies at the speed of sound, it catches up with the waves, producing a sonic boom. Would an object radiating light ever catch up with its wave? Explain.

This has to do with Einstein's 2 postulates of relativity. I think the answer is it won't, but why?
