I listen to a lot of Coast to Coast AM. One of their favorite topics is UFO's and extra terrestrials. I have always been a staunch skeptic. Phil Plaitt wrote this on his blog today, Bad Astronomy. It is a very valid point.
To his list, I’ll add my #1 reason of all time: why don’t amateur astronomers report them in record numbers? After all, who spends more time looking at the sky? The fact that few if any amateurs report them is a pretty clear case that the vast majority, at least, of all UFO reports are misunderstood mundane objects like airplanes, satellites, reflections, meteors, and Venus. Sometimes even the Moon, amazingly.
When a flying saucer lands on the White House lawn, someone call me.
