But at least the 747 achieved Cat 3 certification, which the VC10 did not.
Only the Super VC10s were autoland equipped, not the Standard VC10.
BOAC management tried to pressurise crews into using the VC10 autoland in order to prove the system for eventual Cat2/3 approval, but met with resistance. As Albert Driver says, the line crews rated the need for handling practice higher but also I believe they mistrusted the autoland because of its unreliability.
As I recall a failed autoland or coupled ILS was one of the factors in the BOAC VC10 low fuel diversion to the military field at Bedford. Massachusetts, not Bedfordshire.
