I presume aerodynamics was the reason for having the tail wheel raised in flight but was it worth the extra complication/weight? I can't recall any other tail wheeled aircraft having this facility.
I also note in the Wiki article that the crewing of the Stirling was different from the other four engine bombers. The Stirling had two pilots and a Flight Engineer, as well as a Navigator/Bomb Aimer, compared to the others having one pilot, a Flight Engineer, Navigator and Air Bomber/Gunner. Unless this was later changed, would this have been another reason for preferring Halifaxes and Lancasters?
