The classified missions published landing weights for some reason; they were low; the assumption is they never hauled anything home or they faked the landing weights because it wouldn't matter if they told the truth or not to the public (AFAIK no payload related change in realistically observable flight path was ever seen by independent observers)
Westar 6 was later relaunched as AsiaSat 1. It trips non-space people out because "everyone knows" SpaceX and the old shuttle are the only things ever launched into space, landed, and re-launched back into space, but they were doing this back in the 80s with comsats and who knows what the military was up to.
Of course then there were the soviets launching entire nuclear reactors into orbit for a few months' worth of radar duty. Ok the US did one too but it was just one. All those Russian cores are still in orbit except the two that crashed.
Crazy times.
But then, so does the quality of the images they captured relative to what would be expected given the times.
