This jet-propelled boat was tearing across Lake Windermere at about 70 m.p.h. yesterday when it began bouncing wildly over the swell. Before the driver could slow down the boat dived under water. It reappeared almost immediately but began sinking slowly. Pleasure boats rushed alongside and waterlogged boat was towed to the beach.On Saturday, with Stella Hanning-Lee, 28, at the controls, it was to have made an attempt on the world waterspeed record - 178.49 m.p.h. - held by America. Frank Hanning-Lee, Stella's husband, was driving at the time of the accident. He was unhurt. His wife was driving when this picture was taken, earlier in the day. After the accident Mr. Hanning-Lee said: "There is no damage done and she will dry out in a couple of days." August 21, 1952.
