Can you see anything behind you?

First of all, anything with mass can never travel at, or faster than, the speed of light. In order to do so it would require an infinite amount of energy...in the enture universe, there is no an infinite amount of energy.
Any answer to this question is purely speculative and virtually meaningless in this context since the situation can never occur.
However, some insight may be gained by remembering that no matter the frame of reference, no matter the observer, the speed of light is ALWAYS measure to be constant. Light will always travel at the speed of light...in a vacuum the speed of light is exactly 299,792,458 m/s.
If one were to look in the rear view mirror and make an observation as to the speed of light, no matter one's velocity relative to some arbitrary point in space (since there is no such thing as an "absolute" speed), one will always measure the speed of light to be the same.

Actually, you can't ever fly at exactly the speed of light, though you can get infinitely close to it. If you were moving at very near the speed of light you wouldn't be able to tell. You could still see reflections in a mirror or shine a flashlight in front of you and you wouldn't see anything different. Everything around you would seem squashed though. Things in front of you would look red and things behind you would look blue.

As you approach the speed of light, the stars in the sky seem to shift toward the point in the center of your windshield. All the stars converge there. If you look out the back of your spaceship, you see only black sky.
