What, September 14? Besides the death of Grace Kelly in 1982 and the death of Patrick Swayze in 2009?
Hmm.... let's see... Oh, another death... William McKinley, the 25th U.S. President, in 1901...
Anything BESIDES deaths?...
1994 Major League Baseball season canceled because of a strike...
The first person to fly solo in a hot-air balloon across the Atlantic Ocean, 1984...
First man-made object reaches the moon in 1959 (Soviet probe Luna 2)...
Screw it, nothing really notable. -_-
