On the night before Halloween, 1938, that's what people all over the country heard coming over their radios -- an announcement that a glowing yellow spacecraft had crashed in New Jersey. When the announcer went on to describe an alien covered in tentacles that came wiggling out of it, the entire country panicked!

What most Americans didn't know was that this emergency broadcast wasn't real -- it was a radio play, performed by actors, based on the H. G. Wells science-fiction novel The War of the Worlds. Aliens hadn't landed in New Jersey that night. There was no spacecraft.
