A doctor and his wife were sun...

A doctor and his wife were sunbathing on a beach when a well-endowed, beautiful, young, blonde woman in a tight-fitting bikini strolled passed. The woman looked at the doctor, smiled seductively, and said in a very sexy voice, "Hi there handsome. How are you doing?" before wiggling her backside and walking off.
"Who was that?" demanded the doctor's wife.
"Just a woman I met professionally," replied the doctor.
"Oh yeah?" snarled his wife, "In whose profession? Yours or hers?"

Sir Christopher Cockerell

Died 1 Jun 1999 at age 88 (born 4 Jun 1910).English inventor of the hovercraft. He was an electronics engineer with the Marconi Company (1935-50) where he worked on airborne navigational equipment and on radar. Then he began a boat-hire business. Considering the water drag on the hull of a boat, he had the idea of raising the boat on a cushion of air. In 1954, he performed a crucial experiment using kitchen scales, tin cans, and a vacuum cleaner to show that a stream of air could produce the required lift. The next year he built a working balsa wood model with a model-aircraft engine. The first full-scale prototype, SR-N1, weighed 7 tons and was capable of 60 knots. It crossed the English Channel in 1959 (with Cockerell aboard). Hovercraft entered regular cross-channel service in 1968.
