To go back to the detail of the debate, I cannot see the point of MoD aquiring it's own fleet of 10 civilian operated "vanilla" transport aircraft. It would have no impact on the operational airbridge and would offer nothing that could not be achieved by chartering from the the likes of, as you say, Globespan. If the aircraft cannot go into theatre what would be the point of the investment?
I was just about to make the very same comment, BP!
Whilst there is a downturn in the civil airline market, yielding ample spare leasing capacity, I cannot see any advantage in the RAF acquiring any single role strategic AT assets of its own.
