Keg, I still contend that VIP OPS isn't at all predictable enough for this type of arrangement. Also, if I was GD, I'd be looking at how my pilots are presently rostered if they can be spared for a week here and there to do reserve work.
Agree that cost/benefit needs to be looked at from the Governements side. But I suspect that isn't really the "benefit" that most people here are discussing: "what's in it for me"?
