Am I alone on this??

I've been thinking, and been playing a lot on BoP. And to me, it seems you unlock more planes on the Single Missions, than you do on Campaign? Is it just me, or do you unlock more on the Single Missions. So far, I've unlocked the Macchi 202, FWA5, La-7, and I think I unlocked the Yak-9 on Single Mission? On Campaign, it seems you already fly the plane your going to unlock at the end of the mission. I've been playing through campaign on Realistic and Sim, and haven't unlocked anything new when I get a better score on the mission in either Realism or Sim?
