[@Avanhelsing] That could certainly be a part of your own character's story arc. I need new recruits because seasoned pilots would have known what happened at Dunkirk, thus taking away somewhat from the first part of the story. Said seasoned pilots would also have had their performance and mental sanity severely affected by the incident at Dunkirk. 

145 RAF planes were lost at Dunkirk - in our timeline, let's up that to 200. Let's say out of fear of losing their flying force to whatever the Germans were controlling, only about 800 planes were deployed. That means about 600 pilots came back different men and quarantined. An estimated 3,000 pilots fought for the UK in the Battle of Britain. That's a lot of fresh blood. (Will include this in the OOC.)

Are you guys okay with doing this in Advanced? Standards won't be incredibly high.
