Operating for 19 hours straight Nobody was operating for that length of time. The captain had been awake for 19 hours, the first officer had been awake for 12

  To call attention to my use of the word "operating" in this context, and highlight strict use of the word as ...technical(?) vocabulary, to form a rationale for censure of the general thrust of my statement, is pretty pedantic, and a semantic criticism at best. Nonetheless, I'll put forward, that even if a direct flight from Toronto to San Francisco only takes about 5 or 6 hours, 19 hours, and rounding out the time of day to midnight as a circadian cue, definitely puts the pilot 3 hours past the usual 16 hour limit for bedtime (right, 12 hours for the co-pilot, okay). Both the pilot and co-pilot probably had at minimum another entire hour before they'd even have a chance to wind down and turn in for the night, so pile up the anticipatory nature of having to deplane and get to a hotel room onto their psychological state.
