Initially we had our own Anson which could carry a full V-bomber crew.
And later you had the Bassett which was ideal for this purpose - as long as the crew consisted of five racing snakes! Not sure how it was in the bomber force, but I can think of a few tanker crews who would have severely tested the Basset's take off performance.
(Sorry,
six racings snakes, I forgot the crew chief. As I recall most of our crew chiefs were "built for comfort" too.
