J. Craig Arfons crashed and died during his attempt to set a world water speed record because his hydroplane began to fly like a jet, and with no wings it tumbled out of control, an investigator says. Arfons was traveling so fast July 9 that the boat lifted off Lake Jackson,and Arfons no longer was able to control it, said Lt. Dale Knapp of the Florida Game and Fresh Water Fish Commission. Arfons may have been traveling as fast as 400 mph.
