There was criticism at Lockheed in the early days about the "British" standards of the engine. However ...
The various flight management systems described above, and particularly the autopilot and its autoland capability, were principally concepts by design engineers from the Trident at Hawker Siddeley, who had lost their jobs when development of the Trident, and its pioneering autoland, was run down on completion of the design work, just at the time when Lockheed and its main subcontractors were staffing up for the Tristar. Much was made at the time of the "brain drain" in the UK, which included a number of these key players from the Trident autoland project, who Hawker Siddeley had decided were now no longer needed, and who left Hatfield for the bright (?) lights of Burbank.
The L-1011 on approach partially deployed its flight spoilers.
Is this what Embraer did 40 years later to adapt the E190 for the steep approach into London City ?
