    As some can probably tell I like weird/not so heard of planes. This was built to learn more about short takeoff potentials/limits etc. I belive...

    This was an experiment to investigate Upper Surface Blowing. In 1961 when I was aboard a Boeing 720B during a production test flight we were coming out of an altitude-loss auto pilot turn test over the Olympic Peninsula when we spotted the 367-80 over a cloud deck apparently suspended in space. It was running tests on the 90 degree blown flap configuration for the forthcoming short take off and landing cargo stuff for the XC-14,15,17. It was the weirdest thing I ever saw to see an airplane that size hovering over the clouds with little or no means of support. We were told that it was flying at 80MPH or less. Huge amounts of bleed was tapped out of the engines and ducted back to orifices along the leading edge of the flaps to produce the upper surface blowing to maintain attached flow. Upper surface blowing works great as long as you have symmetry in power. If not, Katie Bar The Door. The stainless steel and titanium flap configuration is still on the airplane as it is in the Smithsonian Museum today. There is 2200 pounds of lead ballast in the nose to make the airplane balance with all that steel in the trailing edge of the wings. The wings are nowhere near what they originally looked like and I would like to see them restored to their proper configuration.
