Out of boredom, I decided to look for available information about UFOs on the official website of the Department of Energy

https://www.energy.gov/nnsa/uapufo-resources-and-documents

In some of those documents i found pretty interesting information about flight characteristics of UFO’s:

” And a Handful of UAP Appear to Demonstrate Advanced Technology. In 18 incidents, described in 21 reports, observers reported unusual UAP movement patterns or flight characteristics. Some UAP appeared to remain stationary in winds aloft, move against the wind, maneuver abruptly, or move at considerable speed, without discernable means of propulsion. In a small number of cases, military aircraft systems processed radio frequency (RF) energy associated with UAP sightings.”

Also read Protective Force Division Operations Reports. Interesting details about various incidents. Also there is a graph “Suspicious Vehicle”.
