It’s been almost a century since the first, primitive experiments with in-flight film projection took place in an Aeromarine Airways Curtis F5L aircraft. It was 1921, and the 11 passengers on a sightseeing flight over Chicago were shown a silent movie promoting the city. But it wasn’t until 1961 that David Flexer’s Inflight Motion Pictures brought regular in-flight entertainment to passengers on Trans World Airlines’ early jets.
