Gotta love an autobiography in which a man will confess to everything he's ever seen, even if it makes him sound a little crazy. Here's David Brower, in his delightful autobiography For Earth's Sake (l990):
When I was eight, walking home one day [in Berkeley], I happened to look up at the sky and saw a brilliant object streak across it, leaving what I would now call a vapor trail. The object itself glowed red and tapered to a point in front. I described it excitedly when I got into the house, but there were no other witnesses and my parents must have thought I imagined it. My first UFO mystifies me still.
Brower's not the only famous person who saw a UFO. FOr what it's worth, so did John Lennon.
