>> years later, dave will have good reason to be thankful for that safer capsule. in the summer of 2009, he enters thunder on the ohio, a race he's won ten times before. in his first heat, another driver looses control and hits dave's boat. dave flips over and smashes into the water. but dave's work redesigning the driver's capsule pays off. it stays in one piece and he waits in safety for help to arrive. >> the only injury i got was a finger injury, where it broken a knuckle in the finger. so as boat accidents go, i'll take that. that's a good one. >> after decades of speeding, crashing, and tumbling through the air, dave says driving a hydroplane is a thrill only few can experience, but many more can enjoy watching safely from the shore.
