Comments: This photograph shows passengers on an Imperial Airways flight from London to Berlin, watching what is claimed to be the world’s first screening of a film in the air. The film they saw was The Lost World (USA 1925). The record for the photograph on the Getty Archive (originally from the Hulton Archive) is dated as 6 April 1925 with the caption “Passengers on a German airline watching the first ever in-flight film”. A live radio broadcast from Berlin supplied the music to accompany the film. However, apparently there was an earlier ‘in-flight movie’ in 1921 on an Aeromarine Airways plane circling the Navy Pier in Chicago, which showed a film called Howdy Chicago to the passengers.
