Black Triangular slow flying object strait overhead blocking out the stars

I can not remember the specific year, but I think it must have been around the return of Halley's Comet or a similar event 1986-1989. I was a young man and remember I had returned from my time in the Norwegian Airforce. I was outside my parents house (I lived there at the time) and was looking up at the complete dark and starry night. What happened next have been following me since that day. And I have not told this to a singled soul, because I did not know how the explain it. I was looking up at the dark sky and noticed a dark shadow approaching, I thought it was a flock of geese flying over me because of the triangular shape, but there was no stars between the V shape when it passed over me without a sound, I then thought it must have been a cloud but it was moving to fast (the speed was like a small plane passing close overhead). The worst part is I cannot remember if I turned around to see where this object went, Or what happened strait after? Then I fou! nd similar stories on this site, now I cannot get this out of my head. I have been working with aircraft and aircraft engines since 1984 to present 2020. And have flown many types of small aircraft including gliders and Hanggliders. I am also a member of the local astronomy club and know what is in the night sky. But this I cannot explain.
