Yes it had Direct Lift Control (DLC) after a certain position was selected on the flaps. That allowed the aircraft to increase or decrease lift without changing the basic aircraft pitch attitude. The autopilot could do great cross controlled landings by lowering a wing and sticking in opposite rudder. I don't know if any curent aircraft have as sophisticated a autoland system. The cockpit was extremely spacious, comfortable and well heated with great views out the oversize windows. Made the 747 cockpit look like a shoebox not to mention stuffing yourself into an MD-80. I'm not up to speed on the 777 or later airbus models.
The galley was "downstairs" reached by two elevators about a third of the way back. Who knows what went on down there. Probably some mile high clubbers and I'm aware of some MJ smoking before the days of drug tests. MK can probably give more info on the lower galley. I used to fly the L-1011 a lot in the Meditterean between CDG and FCO, ATH and CAI or TLV. In addition to JFK to CDG, LHR, AMS, BRU, LIS, CPH, STK, TXL (Berlin) and Malaga. We also flew it to HNL.
