Researching personalities of the early aces

[Lord Bob]

First, this is the best forum on the Internet for someone who just wants to learn more than he can possibly take in in a sitting. Thank you everyone!

Second,

I'm working on some research around the Royal Flying Corps in France in the mid-late 1916 period. There were a few well-known British aces coming into their own around then; Hawker obviously, Wilkinson, Knight (well, British-born), Cockerell, etc. etc. It's easy to find the statistics, victories, and fates of these flyers, but less easy to find anything about their personalities.

Can any of you recommend any books or articles which shed an accurate light on the personalities, rather than just the biographies, of any of the well-known RFC pilots of this period? Feel free to suggest specialist works about one pilot or broad surveys about several; just anything you think might be tangentially helpful.

Thanks so much in advance.
