On a quest to prove to my Dad that the XF5U-1 "Flying Pancake" from SWON did exist I came across a couple of sites that some of you might like. American Prototype Fighters WWII Aircraft Archive Luftwaffe Links
I think there is some bad things said about kotfsc.com in one of the sticky threads, but LRG & LWexperten are both good stuff. I like the flighline myself, but if any info in it seems too fantastic i try to confirm it elsewhere http://www.csd.uwo.ca/~pettypi/elevon/gustin_military/db/index.html is my most used resource. absolutely thourough & i have never seen any wrong info in it....there was a German version of the flying pancake also, i dont know if it got as far along as the US version, maybe only a glider trial, its been a few years since i read about it...maybe it is not such an original idea, just a knock off of the Spitfire's eliptical wings, a circle being a special form of an elipse LOL
