I'm a retired air traffic controller at the time i was not retired. i took my father fishing , at night, on whiskeytown lake, west of redding, ca. we were fishing near the high power lines on the whiskeytown arm of the lake around midnight. we heard a kind of rumbling sound above us and looked straight up. there was a huge black object that was low enough and large enough that it blocked out all the stars from our point of view. we could tell it was flying over slowly, and i thought too slow for that large an aircraft, from west to east toward the city of redding. to our east was a mountain top that it looked as though the object just skimmed over. when it was directly above us you could see a light on the bottom that looked as though it was lighting a wheel well on an aircraft when the landing gear is down. as a controller i knew the telephone number for redding tower so after i loaded up the boat and drove toward home, i called the tower and asked if they knew of any large aircraft in the area. they indicated they did not. i wasn't too concerned because there are many military training routes in the area and at the time beale afb still had sr-71's. i am giving you this information now because i was just watching ufo hunters on the history channel and they were saying that there were sightings of similar objects near corning, ca, around the same time.
