A race car is destroyed in one of the worst crashes in the history of speed hill climbing. Then, a propane gas explosion sends a shock wave more than seven miles away, and one of the world's top acrobatic pilots crashes into a lake crowded with boaters. Also, a semi truck goes one-on-one with a freight train, and tons of concrete and steel crash down on a construction worker.
