High altitude lights
Hello, all.
A few weeks ago, in the middle of the afternoon (14:00ish, ISTR), I noticed what (to me) appeared to be a couple of stars in the sky. They seemed to be stationary. Visible below them were a couple of airliners, which leads leads me to believe the "stars" were at a vary high altitude. I was unable to observe them for lomg, mostly because of broken cloud, and the need to be going elsewhere at the time! The only conclusion I can reach is that they were man made satellites of such a size or albedo that the light reflected made them visible in full daylight. Any satellites I've seen previously have been at night, and to the naked eye, relatively faint. I suppose the other option is that they were aircraft at a very, very high altitude. Can anyone shed any light on this, perhaps? Thank you. -- John Kirkland |

One time at night I observed a high altitude stationary light where no star should have been. I was able to observe the light continously for an extended period of time. suddenly the light moved north at a high rate of speed. This, IMHO, ruled out star, meteorite, and satellite. I have never seen a "UFO". At lower altitudes I have seen similar lights. The souces appeared larger, being at low altitude, and when the light changed direction and came closer it became obvious that this was a commercial aircraft on an approach to an aircraft traffic lane that is a "tunnel" on the flight maps over a large city with heavy air traffic. If the aircraft were at a high altitude such as 50,000 feet instead of 15,000 feet it could have created what I observed in the first sentence. The aircraft would have been travelling straight towards my viewpoint and changed direction. The rate of travel, angular velocity converted into linear for an altitude of 50,000 feet was too fast for conventional aircraft. I did observe a different light many years ago that travelled across the sky for about 10 degress. Similarly calculating speed gave a velocity above conventional aircraft. Several years later when the US's SR-71 was declassified, in part, it became the only known aircraft that would match what I saw. My sighting was at a time when several U. S. Airforce pilots at max altitude and mach reported an aircraft passed way above them at a consideratley higher velocity. The linear velocity of what I saw would match the SR-71 at an altitude above 50,000 feet. The U.S. Air Force would tell you that you observed weather balloons.
