I am still laughing at the idea of putting a propeller under the aircraft to help it stay airborne
Almost as ridiculous as hanging the whole machine from a large propellor and leaving the wings off.
Thats on top - so ok !
But I was chuckling at visualising the Flyer with a large prop mounted horizontally below the aircraft and then having to mount the whole thing on a launching rail
Then of course would be the fun of trying to drive that prop from a horizontally mounted engine and bending the chain drive through 90 deg !
Also then having someone lying under the aircraft to swing that prop for engine start !
Much more challenging than having 2 pusher props turning nice and slowly,and even having them contra (counter) rotate so there is no turning/torque moment on the airframe,now that
was good design philosophy in the early 1900's.
