Did You Ever See a U F O?

Twice... Once 22 years ago: Hovered over the house,about 500 feet up. Oval shaped, white lights. Figured it ,was experimental U.S. forces. The wild part: I went outside to look at it, it hovered & left lickety split without turning around.(changed direction without typically known aircraft maneuvers) . That I can accept... The fact my father was awake & saw it ( did the NASA /Navy/Air Force sub contracts from '55-'88..) He saw it,never said a damn word...
Two weeks ago: Something over the Pacific Ocean,off the California coast. 1-3:00 a.m., P.S.T... something bright white ( no other color lights...). Watching it do altitude drops, 45 degree changes, & climb in a repeated cycle. (This one sounds like experimental U.S equipment. That first one,was just flat nasty..I don't believe that was human based).
