April 23rd is World Book and Copyright Day! Find a joke about it!
A man walks into a library and asks the librarian, "Do you have any books on how to create suspense?"
The librarian pauses for a moment, then says, "Yes, but I'm not going to tell you where they are!"

Ejection seat experimentIn 1912, the earliest known experiment to produce an airplane ejection seat was conducted by Odolek, an Austrian inventor. The trial took place in Issy-les-Moulineaux. It was not until 1941 that the first successful design was produced by Heinlel, a German company. Made 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. A test pilot made the first emergency use of the ejection seat on 13 Jan 1943.[Image: Heinkel He280.] |
