Do enough reading on them there flying machines and you're bound to have come across that.
That litle aircraftt fact hung around in semifamy because of the "orifice" connotations. Tee-hee-giggle-giggle-snicker-snicker.
All kinds of weird things emerge from aircraft history.
Like the Spitfire fighter jet propulsion exhaust stacks whichi increased its speed about 6 mph over the regular Rolls-Royce exhaust stacks. Hey, you blow something thisaway and you go thataway.
And the fact that Charles Lindbergh actually flew (illegally) in combat in the Pacific war, supposedly downing at least one Jap airplane. (His real contribution was in demonstrating how close RPM control could substantially increase the range of fighter aircraft, specifically the P-38. IIRC, this range enhancement allowed us to assassinate Yamamoto. )
And that Claire Chennault was actually a guy. :)
There are times I think somebody ought to market an aeronautical trivia pursuit game.
My source says this thing never flew, but others claim it did. Maybe it was like Howard Hughes' Birch Goose, which some claim was only aloft on ground effect lift.
