UFOs in the Sky - Video Compilation

Footage includes stunning helicopter camera captures of UFOs flying low over downtown areas, a missile destroying an unknown alien orb, an amazing formation of shimmering UFOs in California, and a close encounter on the high seas near Spain.

UFO activity is increasingly more prevalent near our global air transportation infrastructure and military aircraft. Are all of these sightings just top secret military craft? Or is it possible that even just one of them is not a vehicle of human design - then can we as a people truly say that these are "our skies" anymore?
