Use Any Configuration on any Plane
 Select a plane in offline mode with a configeration. Now click on close. 
 Fly the plane then exit the plane. Now choose another plane and don't click 
 on close just click on fly. The configeration on this plane should be the same 
 as the previous one. Works great from when you choose a bomber and a fighter.
