On this day 30 years ago (do the math kiddies) MTV was launched. The first video was "Video killed the radio star" by the Buggles. Now videos are hardly ever played, and only in the wee hours of the morning. In fact, there's not really much to do with music anymore on that channel. It's all reality television, BAD reality television.
On this day in 1774 the element oxygen is discover for the third (and last) time. Joseph Priestley was a British minister who was the first to publish his reports on oxygen, and is given credit for its discovery. There are two other reports of people doing experiments that discovered oxygen, but they didn't get their work published. We can all breath easier.
On this day in 1966 Charles Whitman went on a shooting spree atop a bell tower on the campus of the University of Texas in Austin. He shot 46 people with his stockpile of guns and ammunition. Whitman was an expert marksmen and former marine. 13 people died before Austin police officers stormed the tower and killed Whitman.
On this day in 1943 John F. Kennedy becomes a hero when his boat, PT109 is cut in half by a Japanese destoyer and is sunk. Two men were killed immediately, but 11 were sent floundering in the water. Kennedy saved one injured man by swimming over a mile with a cord to the injured man's life vest in his teeth. Once they reached a small island they awaited rescue, but it didn't come, so they swam to a larger island where they met native villagers. Kennedy was able to get in contact with his base and everyone was rescued. Kennedy was awarded a medal for courage.
