Which begs the question, as to how other sectors are coping ( and will cope in the future ) for example Biz-jets, G/A and vintage aircraft, the last two requiring a different range of skill sets in contrast to those required for the "Airboeing" fleets.
Define skill sets, have done Military, Fighters, Helicopters, Biz-jets, Airliners, Warbirds and do G/A.... Cannot see a lot of difference in the skill set between any of them, if anything G/A requires a greater skill set.
