This is going to sound real dump. About 25 years ago a group of military reservists were assigned to drive a large number of trucks to a field. They were to park them according to a set plan. The were then told to report to the south side of the parking area, lay down and look up.
this was done to test how good a soon to fall from orbit Satalite cameras were. The story was that the Satalite could take a picture of something as small as a silver dollar.
you guessed it. They got the photo. On the north side of the parked cars was a couple fucking. The picture was good enough to get the two kicked out of the reserves. At the time I was working part time in the junior ranks mess as a bar tender. The photo was up for about two weeks before someone reported the pair to one of the NCOs. They were not kicked out for the sex but for not following orders.
