I’m currently 18 days into my June 1917 RNAS 5 campaign, flying a mission every day, even after the offensive failed. I do have the realistic mission rate on, but how realistic is that kind of a sortie tempo for a recon/bomber squadron?

I've read books from RFC pilots who mention doing up to three sorties a day around that period, so from my limited experience I'd say it's pretty realistic. Of course there are many others more read and experienced that could say this for certain.

Somehow, I’ve never had two sorties in a day, even when my squadron still had Strutters.
