John Farley,
One of the stories I heard involved the Victor Training Flight. Not the final conversion unit but the initial one in the mid-50s.
Apparently they used to do long range radar recce sorties to the east. Flying on a western heading at 45,000 feet and 0.9 mach nothing could catch them. The jets from 2ATAF would be launched to delouse them as they came streaming over the border.
