I am an airline captain. My co-pilot and I were on our way from LAX-PDX at FL 380 and we were in the Mt. Shasta area. It was a smooth flight and very little ATC communications were going on. We decided to look out and up at the night sky for falling stars and or satellites passing over head.
We were heading about 310 degrees and to our 2 o'clock high, maybe 50 degrees up from the horizon I noticed 2 brighter than normal stars and mentioned to my co-pilot that I didn't remember ever seeing those 2 stars that were brighter than the surrounding stars in the background. The 2 lights were approximately an inch apart in the windscreen and the size if normal stars. Just as I said that one of the "stars" just dimmed out over about a 10 second time span followed by the other one dimming out completely in about 10 seconds also.
The stars, now obviously lights we not in motion, they were not satellites and were not falling stars. They were as stationary as th! e stars in the background. We were flying in crystal clear skies and were not flying though any clouds whatsoever. These 2 lights were not following the typical west to east orbital path as most satellites do and were just sitting there kind of like ships hiding in plain sight.
The altitude of the lights appeared to be outside of the atmosphere. We were flying at 38,000, approximately 7 miles up and these were at least 100,000 feet up. The thing was they were extremely bright and not moving. Mankind does not have craft that can fly at that altitude and not be moving.
