ahh sorry forgot of course its that easy! so what about all the other procurment issues then!?
Only when the military are involved. Commercially it would be very straightforward to handle, spares, training and the metal.
Perhaps a more effective, and cost effective, solution would be remove the strategic transport task from the RAF and civilianise it. Better service, cheaper.
I don't know how much it costs to run a T* but typically the 744 runs to around $40K per hour assuming LLPs and burdened maintenance at around $3K per flt hour.
