Double Feature! (Apr, 1960)
First class used to be in back?
TO ENTERTAIN passengers on their long nonstop international flights, TIA, a French airline, tried to install movies, but could not make them visible simultaneously on both sides of the partition that separates the tourist class from the first-class cabins. To solve this problem, Pathe engineers in Paris designed a double lens-prism projector which throws one picture on the screen mounted forward in the tourist cabin, and diverts another image to one side toward a smaller screen in the rear cabin. The regular public-address system carries the sound track. The “Pullman berth” folding projector saves space but also provides a shock and vibration-free mount for the projector.
