Harry was finally a groom and was very excited about his upcoming marriage.
He was on his way out of the office when his boss came over to him with an outstretched hand, "Congratulations Harry! I just wanted to tell you I've been married for twenty two years, and I am sure that you will always remember this day with the fondest of memories, as the happiest day of your life."
"But sir", said Harry, a little bit confused, "I'm not getting married until tomorrow!"
"Yeah, I know," said his boss.

First British jet

In 1941, Britain's first jet-propelled aircraft, the Gloster-Whittle E.28/39, flew for the first time, taking off from RAF Cranwell on a historic 17 minute flight. Its jet engines were designed by Frank Whittle, “the father of the jet engine.” The planes of the 1920s were powered by piston engines, with propellers providing the necessary thrust. This was limiting with regards to speed and height. While he was at Cranwell, still only 21 years old, Whittle began to consider the possibilities of jet propulsion as applied to aircraft. By 1930 he had designed and patented a jet aircraft engine. After 11 years, Whittle's engine, tested and modified, successfully powered an aircraft in flight.
