When Harry nukes the Asteroid, the shuttle is bailing with full throttle to escape from the explosion. So we can assume, the shuttle is flying nose first. Yet when the bomb is exploding, the whole cockpit is illuminated from light-rays coming in from the wind-shield!

We all know vacuum does not reflect light, so where did it come from?

Of course the shuttle could fly with its stern forward in space, but do you think they rotated ship 180 degrees to see the explosion?
