Pappy Hartley is "over 40" and General Stoneman is 49.
Presumably after all is said and done, Cobb ends up as the 920th Group Commander as we do not see him again.
On the B-17 at the start of the episode the pilots are Miller & Ditchik.
Very much like "Eddie Rickenbacker". Hartley holds a Distinguished Flying Cross, Distinguished Service Cross, Croix de Guerre.
Hartley was a WWI ace, flew with the Hat in the Ring Squadron, retired a Captain and came back as a Colonel .
