The Trident and the VC10 were the first airliners to be fitted with Autoland
The VC10 autoland really didn't begin to compare with the Trident system.
The Trident had a triplex autopilot system perfectly suited to a failsafe autoland operation.
The VC10 had dual autopilot which was never going to deliver autoland reliably on a fleet where handling practice was in far too short supply for line pilots to practice using the system, on routes that only very rarely required its use.
I'm tempted to state the dual autoland on the earlier 747s was even more suspect than the VC10 system, as November Oscar demonstrated at Heathrow.
But that might start an argument.........
