It hit the plane on the front. Doesn't something like a bird that flies at a stable altitude increase the chance of a collision on the front?

If you're traveling at 500mph, any relatively stationary object is likely to hit you on the front.

I agree, but meteorites or satellite debris have a big vertical velocity and are more likely to hit on the top.
