Hi Geroge: Yes, it seems was this way also, hated by the cabin crew loved by the cockpit crew. Up front the guys had autothrottles. But one of the crews (Aeromexico) used the AT not accordingly the procedures until the -10 lost lift and control, entered a prolonged stall plunging for 11.000 ft. aviation-safety.net/wikibase/232857www.ntsb.gov/investigations/AccidentReports/Reports/AAR8010.pdfThe final report blamed the crew for not using standard operating procedures (speed or mach hold) instead using climb rate, paid no attention to the instruments and misinterpreted the stall buffets as engine problems for one minute until finally executed the stall recovery. All together: High altitude flying in jets is not a piece of cake even for a crew with more than 30.000 flight hours between them. Kind regards Walter P.S.: A big BRAVO for the aerodynamics of the -10, which even with asymmetric thrust selected by the crew did not spin. And a BRAVO also that an elevator did not disintegrate thanks to its sound structure.

It did when high altitude MACH cruise was "reduced" .... again as an early to mid 70's fuel economy measure following the oil price shocks of that period.
AIR NZ (in particular) also more rigidly controlled cabin temperature and air conditioning too in order to initially further aid fuel economy .... or so I recall reading during the early to mid 1970's.
