True Left

I have no problem with using flying in war against our enemies. But flying was irrelevant to the Neolithic Revolution. Therefore it is incorrect to refer to it as Aryan in an evolutionary sense (what this subforum is about).

Regarding energy, you are referring to gliding, but that is only possible after considerable horizontal speed has been built up, and then there is the issue of changing direction (as would be frequently necessary for farm labour). These are what flapping wings are for, which require similar energy conversion to walking, but in much greater quantity, as energy must be wasted to lift and support body weight. You would have to flap your wings a lot to do the same amount of farm labour in midair (and even more if you are carrying stuff around all day).
