This is the illustration from a full-page ad from the Hughes Aircraft Company in the Jan/Feb 1966 issue of Information Display magazine.
This isn’t selling a product — at least not directly. Instead, it’s looking for engineers to make the instruments that air-traffic controller is using to track the progress of that zippy looking radar aircraft overhead, scanning what I think we’re meant to understand is an enemy base, nestled in the mountains.
HUGHES Aerospace Divisions wants YOU!
One of the positions they need filled is “Precision Film Transport.” This was an era when high-tech electronic equipment would capture images on film … you know, transparent plastic coated with a sticky layer of light-sensitive chemicals … which then had to be taken from whatever camera or lens arrangement to whatever processing laboratory could develop the film in conditions of total darkness, or else the exposures would be ruined. This was how, for instance, images from outside the TV studio got put on the evening news. A whole industry of experts in lightproof packaging, with carefully taped canisters speeding along to darkrooms where it would be safe to finally develop the images.
Nowadays, we just point our phones at something and post it where the world can see it.
