Doctor William Christmas believed that struts were unnecessary and that an aeroplane's wings should be free to flap like a bird's. Unfortunately, on the first flight of his 'Bullet' fighter, also known as the Christmas Strutless Biplane and by other names, the wings did exactly that and then came adrift. The pilot was killed instantly. A second Bullet did exactly the same thing a few months later. Christmas claimed all sorts of things, among them that he had 'hundreds' of aeronautical patents and that he was swamped by orders for Bullets from Europe and by million-dollar offers to rebuild Germany's air forces. None of them were true, but he did get the US Army to pay him handsomely for his wing design. Or so he said.
