military research is not the same as war. Flight was developed by the commercial sector.

the people blabbering about war as a means of national rejuvenation are usually the ones not planning on bleeding out in a muddy ditch. 30 million people died in WWI and not much was rejuvenated

Can't speak for everyone, but your second point is an easy one for me. If I were drafted, in any remotely realistic circumstance I would go.

And military research is a result of war or potential war. And if you want to deny the lack of the military's influence in human flight, I'm not even sure what to say to that. Aircraft were adopted by militaries around the world as soon as they were viable. And military observation balloons go back to the 18th century. The military may not have invented human flight, but they funded a crap ton of it.
