Several people have reported spotting a huge UFO in the city of Stephenville, Texas. Some eyewitnesses say it was a mile long. Authorities say it was an illusion created by two airliners. Who has it right? Do you believe in extra-terrestrial visitors? Do we humans trust our eyes more than we should? Is this a fuzzy latest photo of the UFO or a cool painting? Are classic rock stations going to ruin any chances SETI has?
