Have you or anyone you worked with ever seen any UFOs on radar? That is, anything that you knew wasn't a plane, but you didn't know what it was, even if you didn't think it was of extraterrestrial origin.

This is why I think reports from pilots and ATCs are so interesting. Presumably these people are familiar with most every type of craft and corresponding radar signature you would encounter. Cases where a visual is corroborated by an atypical radar signature are the most interesting.
