His “lab” was basically all about testing and simulating environments for the instruments. He had tons of sayings about not having room for error in his line of work. This is as close as you can get from “building bridges” and to this day I don’t think I have seen this level of attention to detail/perfection in any other profession.
His job involved electronical engineering , mechanical engineering and programming amongst other things, not to mention a deep knowledge of the physics of these environments.
Back then also the tools or source of information that were available to them were quite crude compared to what we have now.
His spare time was all about flying, pimping his ham radio gear with all kind of “home made” electronics, build antennas and messing with computers. I guess he’d qualify as a “Hacker” nowadays.
