Used Car

It was a small town and the patrolman was making his evening rounds As he was checking a used car lot, he came upon two little old ladies sitting in a used car. He stopped and asked them if they were stealing the car. They said "Heavens no, we bought it."
He said, "Then why don't you drive it away".
Each of the women said "We can't drive".
The officer momentarily shook his head and then asked "Then why did you buy it?"

Ejection seat first used

In 1942, the first use of an ejection seat to save a pilot was made. Helmut Schenk, a German test pilot, required its use when his Heinkel He 280 refused to separate from the tow aircraft due to the cable release mechanism icing up. As a precaution, Schenk ejected and landed safely. The tow was being made because the He-280 was powered by two Argus pulse-jets that required a high forward speed to start up. The first ejection seat was made by Heinkel, for the He 280. It was powered by compressed air, and accelerated the pilot upwards at between seven-g and nine-g. The He-280 was the first twin-jet engined aircraft and the first jet aircraft to go beyond prototype stage. The earliest known experiment to produce an airplane ejection seat took place on 12 Dec 1912.[Image: Heinkel He-162 ejection seat.]
