My favorite quote of the article:
Southwest is only just beginning to migrate from its traditional “round-dial cockpit philosophy”, which until recently dissuaded its pilots from using autopilots or autothrottles installed on their ‘next-generation’ Boeing 737s.
“Instead,” reveals Hughes, “the company standardised on the classic 737 cockpits and even installed metal covers on the switches of equipment it didn't want its pilots to use.”
