About once a month my wife makes cookies for one of the last surviving Apollo team, who was a patient of hers. Like the others he was a test pilot first, then became an aeronautical engineer, then entered the astronaut program. Although he was an alternate who never went on one of the actual moon missions himself, he was directly involved in designing both the guidance systems and in training other astronauts relative to design specifics. He claims each Apollo craft was specifically tweaked to be ideal for the specific members on it, and they respectively trained on an exactly matching model of craft. I've discussed the cameras a bit with him, but he is a lot more interested in other things. Anyway, those missions were a long time ago, and even the famous shot of Earthrise was a bracketed guess in terms of exposure. We might as well be talking about who allegedly made the best horse buggy in the 1860's.
