Conscription in US was enacted May 18, 1917 under Woodrow Wilson, and terminated November 1918 when WW1 ended. I don't think anyone was drafted. However, it paved the way for future conscriptions. I see a clue of accuracy regarding your description of flight crews, Telemaster, extending beyond WW1, a better way of life but expected life expectancy was oft counted in months.
The Japanese considered the Mitsubishi G4M Navy Type 1 attack bomber a "one shot" aircraft. My college fluids dynamic professor, Dr. Chai told us of his enlistment in the Japanese Army during WW2. He being Korean (Japan had captured Korea and was conscripting young Korean men), took their battery of tests. Then he was given the choice of being 1) Radioman, 2) Bombardier, 3) Mechanic. He thought, "Radioman and Bombardier fly out, don't fly back." He choose mechanic and spent the rest of the time until wars end as that.
