Discussion of R. Nimfuhr's new, but already tested, theory of dynamic flight, according to which pressure of air is utilized as supporting force. Describes how a constant atmospheric pressure wave is generated on which airplane sails with much less consumption of power than would be the case with propeller drive. Describes how with Nimfuhr flight theory, gravity can be overcome with employment of a single man power (equivalent to 1/5 hp.).
