Watch as a midget car racer crashes and flips several times, then is trapped as the car explodes and engulfs him. Next an 8,000 square foot mansion is sucked into a sinkhole in the hills of San Francisco. A flight instructor is showing another pilot how to recover from a "spin" in a training jet when it spins violently out of control and the ejection system fails. Then a hydroplane speedboat crashes at more than 200 miles an hour. The boat disintegrates, the drivers' capsule fills with water, flips upside down and the driver is drowning while still strapped in his seat. Will a pregnant skydiver survive crashing face first in a parking lot? Finally a helicopter on a rescue mission crashes and erupts into a fireball on a rugged mountain range. The six men on board scramble for their lives and one of the crewmembers is pinned under the nine ton chopper.
