"On February 7, 1981, the Beechcraft Bonanza A36TC Wozniak was piloting crashed soon after takeoff from the Sky Park Airport in Scotts Valley, California.[59] The plane stalled while climbing, then bounced down the runway, went through two fences, and crashed into an embankment. Wozniak and his three passengers, then-fiance Candice Clark, her brother and his girlfriend, were injured. Wozniak sustained severe face and head injuries, including losing a tooth, and also suffered for five weeks after the crash from anterograde amnesia, the inability to create new memories. He had no memory of the crash, and did not remember his name in the hospital or the things he did after he was released from the hospital.[15][60] The National Transportation Safety Board investigation report cited premature liftoff and pilot inexperience as probable causes of the crash.[61]" - http://en.wikipedia.org/wiki/Steve_Wozniak#Airplane_crash
