46 foot catamaran goes air born and flips during a race in Key West on 11/09/11. Drivers Robert Morgan and Jeffrey Tillman are unconscious and underwater when helicopters fly in and drop rescue divers. Both drivers on the boat died later at the hospital.

Superboat International President John Carbonell said he witnessed the crash, which occurred adjacent to a spectator area.

"He was probably going about 130 mph and the boat's propellers were barely in the water," Carbonell said. "The boat apparently caught some air and went bow (front) up; straight into the air, came down and went backwards."
