I agree that he has certainly made it his lifetime obsession. But unlike some people's crazy or fantasy obsessions, Al Bowers is absolutely not putting opinion before science, or his hoped-for outcomes above fact. There are far too many highly educated people who have watched his progress... if a high level guy like Phil Barnes, and a whole room ful of experienced aerospace people as well... thought that Al was not being accurate, they would be in a position to call it into question. As far as his lift distribution and wing twise implications, Al's work is also somewhat supported by work from Irv Culver (The "Culver twist" for flying wings),a nd Jack Norris' propeller twist distribution research, all of which is based upon a lot of early mathematical research by people like Prandtl who have no stake in this argument (being dead) A pure flying wing is a noble goal, and perhaps the theoretical beauty of that is what motivates Al and many many other nurflugel people. But Al himself answered a direct question I asked... "Yeah, this would work just as well on a Cub".
