Keith’s note: By now you’ve heard all the goofy talk of a comet from outside our star system that might be an interstellar spaceship coming around the sun. I was reminded of something else that happened on this date – 30 October 1938: The infamous “War of the Worlds” radio broadcast by Orson Welles and the Mercury Theater. It drove a lot of people slightly nuts – including my grandmother. She listened to the broadcast along with my father on this Croydon AM/Shortwave radio. And the radio still works. If the comet sends a probe toward Grovers Mill, New Jersey, be scared. Very scared.
