While I cannot claim any knowledge of aeronautics, I don’t see how the boomerang could “pave the way” for flight unless it can be shown that the Wright brothers or other pioneers of flight had studied the boomerang.
More “diversity” nonsense.
Exactly. Real pioneers like Sir George Cayley, Octave Chanute, Dr. Langley, and Otto Lilienthal studied bird wings, and extensively documented their studies. No mention of boomerangs.
(The Wrights, by the way, contributed almost nothing to the design of their successful first plane. Were it not for an accident with the launching catapult, Dr. Langley would be celebrated as the first to fly, as Glenn Curtiss subsequently proved, and the Wrights would be unknown also-rans.)
