Unfortunately, they have tried the FJ restream route on a couple of ME fleets, and unfortunately, it hasnt worked out fantastically for a fair few of them. All top chaps of course.
The RAF AT fleet is already desperately short of deep down experience, of the sort that is going to be lost in droves to the airlines in the very near future. That is going to leave us post 2015 with an air force all of a sudden supporting ops and exercises globally, to places like norway and canada, belize and the FIs and the far east, flown by captains that have never used type 4 deicing fluid and landed on an ice runway, or operated through the ITCZ.
It could (I suspect if we will lose a frame, it will be post-op) be the most dangerous phase of the high op tempo that we currently are experiencing, as those currently building egos doing the same sh8t day in day out will discover AT Ops can be a damn sight more dangerous operating in cold conditions for the first time, or through a line of CBs, or applying a massive temp correction to your plates, as opposed to your 200th Bastion/Kaf landing.
