Yes the RAF were using several types at the time in Transport Command, the Beverly, the Argosy ( whistling wheelbarrow ) the Andover , the Britannia, and the Belfast, also the Comet 2 and 4 the Beverly was phased out once we started re equipping with the C130 also the Argosy went too, the Belfast stayed in service until around 1977 I do remember my Father who was a Flight engineer on Britannias praying not to be posted on to a Herc Squadron, as he disliked the C130 for some reason, I never did find out why, So after the Brits were retired from service, he was posted fromm 99 Squadron at Lyneham, to 53 Squadron at Brize Norton, and he went on to fly on the Belfast, an aircraft he loved almost as much as the Britannia, when the Belfast was demobbed in 77, the RAF in their wisdom decieded that a Master Flight Engineer, who had served from 1942 until that time, and only had about 18months of service left before mandatory retirement , that they would post him to a VC 10 squadron, my Dad was horrified and mystified at the same time, as he had never flown on Blow jobs, as he always said a good screw is much better So he banged his notice in and ended up flying with Heavy Lift on the Belfast so he was a very happy bunny indeed.
