Talk about thread drift. Ever since post 3 this has been heading off at at tangent from the OP. Non-Traditional Aircrew are mission specialists such as FC, IA or AT, nothing to do with stewards or movers. They have done at least a course in Aviation Fundamentals at Cranwell alongside the Generic WSOp students before specialist training on type. Since the established rear crew trades were all amalgamated into WSOp, should there be a one size fits all Mission Specialist flying badge too? Or since they are so different, maybe keep them separate and let some of the old badges make a comeback - N, AE, LM for instance?
