Answer 9

A vehicle used for space travel .We don't manufacture that particular model of flying vehicle, so when some one sees a UFO, they can't identify it(of course) and that's why it's called an unidentified flying object. (life forms ride in it too!)

Answer 10

My wife and I saw one a few years ago. I grew up on an air base and flying small planes so I am familiar with most military and civilian aircraft but not what we saw. I think it was probably military and we will probalby know what it was in a few years. It was cool to see anyhow.
