Sorry
gums, but I have to trump both of those!
Our Viper had ZERO mechancial connections of any kind to the flight control surfaces.
You are about two decades late!
An aircraft with 'ZERO mechancial connections of any kind to the flight control surfaces' first flew on 30th. August 1952. It was the VX770 prototype for what became the Avro Vulcan.

The term used for electrically controlled hydraulics with feedback was 'Powered Flying Controls'. The 'Controls' even had 'autostabilisation in the form of pitch and yaw dampers' and later an 'auto mach trimmer'.
As with FBW, loosing electrical power was critical - 'Because there was no manual reversion, a total electrical failure would result in a loss of control.'
Interestingly the Vulcan was powered by Olympus engines, which later were to power Concorde.
A Vulcan airframe was used as a testbed for the Concorde engines.
Re-reading the Wiki highlights that many safety features that are currently used were developed for the B2 variant of the Vulcan (RAT, AAPP->APU).
The Vulcan is of the same vintage as the De Havilland Comet - the first commercial jetliner, yet some of it's engineering developments took many decades to appear in commercial jetliners!
