Just watched a show on the Columbis disaster, and a question came to me.
Why does the shuttle have to be travelling so fast to re-enter the
atmosphere?

Think of it this way. The shuttle isn't moving fast, its landing on a
fast moving object. Landing on the earth is like a carrier landing,
the earth is spinning around and the shuttle has to match to it.
