A saxophone player was contracted to do a recording session for a movie. Much to his delight, the soundtrack was pretty much a sax solo from beginning to end.
When the session was over the sax player asked the producer what film his music would be in. The producer admitted that it was an adult film and gave him the name of a theatre that would be showing the premiere.
At the premiere, the Saxophone soloist crept into the movie house, embarrassed, and sat in the back next to an elderly couple who were also trying to be anonymous. The movie was disgusting, ending with a scene involving a dog. The sax player finally had enough, and made his exit past the elderly couple, remarking, "I only came to hear the music."
The old lady replied, "We only came to see our dog!"

Solar-powered flight

In 1980, Steve Ptacek in Solar Challenger piloted its first solar-powered flight. The aircraft was designed and built by AeroVironment, Inc. (founded in 1971 by ultra-light airplane innovator, Dr. Paul MacCready). An earlier, 71-ft wingspan, solar-powered design, the Gossamer Penguin, after test flights, flew about 1.95 miles at a public demonstration on 7 Aug 1980. Solar Challenger built upon this experience to be a piloted, solar-powered aircraft strong enough to handle both long and high flights when encountering normal turbulence. With only a 46.5-ft wingspan, it had a huge horizontal stabilizer and had enough wing area for 16,128 solar cells. After design modifications, Ptacek flew across the English Channel flight on 7 July 1981.
