US military jet had encounter with 'silver UFO the size of suitcase'

Videos released by the Pentagon last month show numerous unidentified objects flying through the sky.

New details have been released about encounters between US navy aircraft and "unidentified aerial phenomena" after the Pentagon declassified three videos last month.

"Hazard reports" from the Navy Safety Center, first published by the website Drive, reveal an incident where a pilot encountered an "unknown aircraft" which was "approximately the size of a suitcase, and silver in colour". During the encounter in March 2014, a navy jet "passed within 1,000 feet" of the object but could not work out the identity of the aircraft.

The pilot "attempted to regain visual contact with the aircraft, but was unable", the report said. The documents follow the release of three short videos recorded by navy pilots in November 2004 and January 2015. In one video, a dark circular object is seen flying in front of a jet, while another shows a small object speeding over land. The final video clip shows a circular object moving quickly before appearing to slow down.

A voice in one of the videos can be heard saying: "There's a whole fleet of them."

Another voice adds: "They're all going against the wind. The wind's 120 knots to the west. Look at that thing, dude!"

UFO enthusiasts were already aware of the videos, which had been circulating online, but it was the first time the Pentagon had released the videos officially. The newly released documents seem to identify a number of the aircraft as drones, or "unmanned aerial systems (UAS)".
