Wow so interesting to read about Col Howard Willis playing a major role in this, being a former Lafayette Escadrille pilot! (?) if I'm reading that right? So it sounds like they didn't get clapped out fighters after all. They were also fighting hard in one of the most difficult periods for the Allied fighters, and engaging with Fw 190s. 33rd Fighter Group, to which they were attached, had a lot of problems when they first encountered these types. GC II/5 didn't have much time to learn the type though they were at least familiar with it's ancestor, the H-75.
