Supplementing resources is a good idea as our strat fleet are over-worked and under-funded (as is everyone!!) as well as working with massively outdated kit (C17 excluded)
Completely replacing resources with civilian contracts is just irresponsible as the lack of flexibility, training and specialist knowledge could prove fatal to both crews, and passengers.
The line defining Strategic and Tactical is a wee bit blurry these days. What would have been a tactical sortie only 2 years ago, is now considered a routine strategic mission. It doesn't mean it's any less challenging or dangerous, only that it has to be done so often that it has become "routine".
