I visited the DA just yesterday. Took me awhile but realized something was wrong. After a few sorties from A1 I figured it out. I kept having this irresistible urge to climb. It was a few sorties later I noticed A1 was Rook, when did that change??? I was always Knight, or at least the last time I visited the DA.
Anyway, I spent most of my time chasing down and killing Tempests, got three of them in my dweeby spitfire, pretty sure I was flying the Mk V and IX. For the record I did take-off in a Tempest once, and didn't head-on every plane I met. The same pilot kept trying to ho me, easily avoided it and then reversed and chased it. Inexplicably the Tempest would try to climb much to early and I was able to shoot it down. Which resulted in much whining from the Tempest pilot and many LoL from me.
