Hambling Chaos & Running In:
Do you really think it would be a wise move to kick start your brand new fleet with a brand new aircraft type?
I can't think of a single 'new' type that has ever been introduced without 'teething problems'. That might be a pain in the backside when you are introducing one new type amongst a couple of other fleets, but when it is your only type, that could spell the end!
