The Department of Defense has released a video from 2015 showing Navy pilots encountering what appears to be a UFO. They're flying just off the East Coast when their tracking system locks onto something below that's traveling at a very high speed.
Both of the pilots admit they have no idea what it is. And in a later interview one pilot said it was "not from this world."
WARNING!!! There's an F-word at 1:42.
The actual video kicks in at 1:22.
