I haven’t been able to crack 20 kills and last more than 3 months. Presently I have a Pup pilot with 18 confirmed out of 34 claims with 66 Squadron. He started beginning of March 1917, survived Bloody April and is now flying in late May. I’ll see how far he goes. Another pilot with Jast 2 who has 12 confirmed started in September 1916 and ias closing in on 90 days survival. Mind you I have Captain Owen Triggers in his Be2c who started operations in 01/1915 and is now in March, so again just 90 days at the front. That would be the extent of my best score and career duration for my current pilots with experience. I have a french pilot and a DH2 pilot (3 kils) who have only been at the front for 45 days. Voila.
Cheers!,
