This book, which I found in the public library, expresses a different
point of view regarding aces in World War One.
The Dream of Civilized Warfa World War I Flying Aces and the
American Imagination

(quoting the Amazon blurb

During World War I, air combat came to epitomize American ingenuity,
technological superiority, adventure, leadership, and teamwork.
Robertson reveals how the romantic and chivalric imagery associated
with flying aces was a product of intentional propaganda and popular
culture. Examining aviation history, military battles, films,
literature, and political events, she looks at how the American
public's imagination was shaped-how flying aces offered not only a
symbol of warfare in stark contrast to the muddy, brutal world of the
trenches, but also a distraction to an American public resistant to
both intervention in a European conflict and the new practice of
conscription. (end quote)
