This flight of fancy, with its vibrating set of wings for propulsion, reminds me of the Japanese “bumblebee” fliers in H. G. Wells’ 1908 The War in the Air (tons of invention, badly written, with a lead character less of a protagonist and more an accidental point of view). Of course, the bumblebees were mounted and ridden like a flying motorcycle, where this is bigger and more conventional. “Flying mounts” rather than “flying carriages” have long appealed to us, as something closer to being winged ourselves, or at least riding Pegasus: they appear in 1827 in The Mummy!: Or a Tale of the Twenty-Second Century by Jane Loudon. However, this one appeared in the December 1931 issue of Popular Science Monthly, p.63. Mad science had not deserted aeronautics after all!
