Can anyone tell me how far back military experiments with Flapping
Flight go? I am interested in why Soaring flight is so rare in nature
but so popular with us?

Have you never watched eagles, buzzards etc soar?

I've heard that the Wright Brothers patented
Wing Warping (Flapping) and never let anyone develop planes using Wing
Warping flight.

Wing warping was for directional control not for lift.
