I always feel so clueless about the things my DS talks about at the Academy. His latest - Airmanship. He was slotted for Jump and then was informed that everything was messed up and they redid the schedules for this summer. He now has Space (I don't know what that is or even if it is considered airmanship) and is very disappointed as he was thrilled to get Jump in the first place. My main question is this: Why won't they allow changes to the summer schedule once its made, even when he knows of people having to drop Jump for various reasons (ie. injury, separation, etc)?
