A wife comes home late one night and quietly opens the door to her bedroom.
From under the blanket, she sees four legs instead of just her husband's two.
She reaches for a baseball bat and starts hitting the blanket as hard as she can.
Once she's done, she goes to the kitchen to have a drink.
As she enters, she sees her husband there, reading a magazine.
He says, "Hi darling, your parents have come to visit us, so I let them stay in our bedroom. Did you say hello?"
HelicopterIn 1946, the first commercial helicopter, the four-seat Sikorsky S51, single rotor helicopter first flew. It was the first Sikorsky helicopter to be licensed by the U.S. Civil Aviation Administration for commercial operations. The world's first commercial sale was confirmed, with deliveries in Aug 1946, to Helicopter Air Transport of Philadelphia. It marked the end of the first phase of the helicopter's evolution. The design established would be followed by others to this day. It could carry 3 passengers over 250 miles at a speed of 100 miles per hour. The S51 had a 15 m span 15 m, and a length of 12.5 m. |
