It was a summery night and I was back from work. I was in the drive way and was very tired, so before getting out to open the garage door I decided to open the driver seat and lay down to relax in the car for a few minutes. I also had my sun roof open and was watching to spot any shooting starts. I then realized that very faint and dark rectangular/cylindrical objects were flying in the sky from south to north, very fast. They made absolutely no flight noise; saw approximately 50 of them flying after one after another at the same speed. After about a minute, there was no more flying objects to be seen. Waited another 10 minutes, examined the entire sky from outside the car, nothing unusual to be found.
