Two students were arguing when...

Two students were arguing when their teacher entered the classroom. The teacher says, “Why are you arguing?” One boy answers, “We found a ten dollar bill and decided to give it to whoever tells the biggest lie.” "You should be ashamed of yourselves," said the teacher, "When I was your age I didn’t even know what a lie was." The boys gave the ten dollars to the teacher.

Radio compass

In 1920, a radio compass was used for first time for aircraft navigation. In a test of the radio compass as an aid to navigation, an F5L left Hampton Roads and flew directly to the battleship Ohio (BB 12), 94 miles at sea in a position unknown to the pilot. Without landing, the plane made the return trip to Hampton Roads, this time navigating by signals from Norfolk.
