I just watched an old Howard Hughes' made movie, HELL'S ANGELS, produced and directed by Howard Hughes (and a few others ... production problems++++) made in 1930. It's a strange film .... mostly B&W, some tinted, and maybe 8 minutes of color. Inspired by William Wellman's 1927 film WINGS, the first Academy Award winner, HELL'S ANGELS featured some great dogfights between WW1 aircraft, and what can only be described as a bizarre, spooky air raid on London by a German zeppelin which did not end well for the dastardly dirigible. Part of its crew tried to save the thing by plummeting to their deaths ..... I sort of wonder if the Krauts had fallschirms in 1917 ....
Check it out. It's on DVD.
