Fascinating and well-written article; thanks! So far just skimmed but can’t wait to read every word!
Question: you stated that there were 2 flight cameras per mission. We’re there additional qualification articles too? In other words, what was the total production? If there were others where are they?
There were 2 made available per flight in case it was damaged. I heard today that during a walk through a NASA manager damaged a camera before a flight. Where are the extras: do you remember "Raiders of the Lost Ark" warehouse?
Also, did the design evolve or remain stable through the various missions?
I am aware of making the base broader to avoid tip-overs, tilting the handle a few degrees to make it easier to hold, and adding a dust cover that allowed the ALSCC to stay out side between multiple EVA on the surface. Buzz Aldrin and Neil Armstrong tested the camera on Earth using their flight gloves and didn't any problems. After the flight they requested the base and handle change, There is no testing like the real thing.
The operational design and the mechanics and electrical components all worked fine so there was no reason to make changes to them. Do it right the first time. The pre-flight reliability testing was comprehensive so there were few surprises.
I love the idea of a return-to-sender label!
