In a conversation, a guy told me that he remembered as a kid flying in a propeller airplane. When people went to the toilet and flushed, a little trap door opened and the waste was ejected into the sky. I do not know if this was the actual case or if he had a false memory from a long time ago. If crap really fell from the skies, would there not be a hit on a pedestrian once in a while? Even a hit of a wad of wet used toilet paper is not too pleasant.
I think that waste was collected into a holding tank and removed when the flight was over, like it is today on jet aircraft.
