I found out that historically the “Fly boys” were Americans who volunteered to enter the first world war early (Rapture implications).
 
There were 38 of them to do so.

The aim was to have their efforts recognized by the American public and thus hopefully to rouse interests in abandoning neutrality and join the fight. (first fruits leading to a larger harvest)

The first major action seen by the squadron was at the Battle of Verdun. The squadron suffered heavy losses, but its core group of 38 was rapidly replenished by other Americans arriving from overseas. So many volunteered that a "Lafayette Flying Corps" was formed in part to take the overflow. Altogether 265 American volunteers served in the Corps. (increasing harvest)

On September 23, Kiffin Rockwell and Raoul Lufbery took their Nieuports (now equipped with the latest British interrupter gear) to the the front. They became separated and when Rockwell jumped a two-seater, its rear gunner sprayed him steadily and brought him down.  – September 23rd this year is Rosh Hashanah!
