I know this isn't totally on topic, but I have a good one from WWI. (This is from the book "Legion of the Lafayette" by Arch Whithouse (link))
An American pilot, whose name I have forgotten, had recently joined the Lafayette Escadrille (or the USAAS, I can't remember) and was up showing the others just 'what a Nieuport could do'. After several hair-raising banks just over the hangars, he climbed until he almost stalled, and then dove vertically at the ground. At the last second he pulled out of the dive and began to loop, the Nieuport screaming in protest. At the top of the loop, the interesting noises became louder and louder. "I wonder what is happening," he said. He had his answer at the bottom of the loop, when the bottom port wing broke off. He glided his now-legendary three-wing Nieuport over the ext hill, and there was a distant crash. When they arrived, expecting to find him dead, they found the Nieuport with only minor damage. Not far off, the new pilot was giving a lecture on aerodynamics to a group of bewildered peasants.
Sorry for the long post.
