43. Sightings over the US
Pilots offer our best source of anecdotal data when it comes to UFOs. To the common observer, a zeppelin or a weather balloon might look like one, but pilots have unique knowledge of the shape and aerodynamics of airframes and are experts in the maneuvering capabilities of aircraft as allowed by simple physics.
Pilots seeing UFOs is not something localized to WWII either, as in the case in 2004 when an F-18 out of San Diego captured spectacular footage of a “tic-tac” shaped object flying at speed. “It accelerated like nothing I’ve ever seen,” the pilot told The New York Times. “I have no idea what I saw.” It seems foolish to think it was an American superweapon, effectively meaning the pilot was tricked by his own government. But they’re out there in many shapes and forms, and since not one pilot has been able to successfully make contact with foo fighters of UFOs (as far as we know), the instances in WWII and since remain a mystery.
