Did You Ever See a U F O?

Talked to an OLD radar operator a few weeks ago. He picked up some work as a security guard on base. When I have duty, I can talk for a while. The moment he told me he was a retired radar operator I asked him about ufo's. He said, "oh yeah, they're real. There was a certain denotation in the radar that indicated when the radar hit metal." An argument could be made for high-end classified US air craft being responsible for the unscheduled radar pings. Allot of radar operators have stories about tracking craft that behave in a way that modern craft simply cannot.
