Ratcliffe added that government officials have attempted to find a "plausible solution" for the UFOs — but admitted "there are instances where we don't have good explanations for some of the things we've seen."

"There have been sightings all over the world," Ratcliffe explained. "When we talk about sightings, the other thing I will tell you is, it's not just a pilot or just a satellite, or some intelligence collection. Usually we have multiple sensors that are picking up these things, and some of these are unexplained phenomenon, and there is actually quite a few more than have been made public."
