This guy doesn't know what he's talking about. Tesla's flying stove was an electro-momentum device. The same technology they use today to build all those flying "UFO"'s. It was not a mechanical device.
William Lyne explains all of this in his books and even shows you how it all basically works.
"Pentagon Aliens" & "Occult Ether Physics"
The Tesla Flying machine was build tested and working years BEFORE the Wright brother's ever flew at Kitty Hawk.
At that point of time, the top physicist were all working to tie together electricity and momentum... Tesla was the one that did it with his "Dynamic Theory of Gravity".
Von Braun, the Nazi scientist worked with Tesla in the 30's and here's his sketch that he made in copying Tesla's idea.
He later went back to the Nazi's in WWII and made all the Foo Fighters that flew circles around the allies planes.
Here's a little tung in cheek movie Lyne's son made ...
