This gripping video looks like something out of a Hollywood blockbuster, but it's all too real.

A construction worker was trapped on the ledge of a building under construction as it caught fire in Houston.

Amazingly, the man doesn't seem to panic. First, he miraculously jumps one floor down and then hangs in there until a rescue ladder saves him shortly before part of the top floor comes tumbling down.

It's absolutely breathtaking.
