Perhaps the voyage report stating that he had not had suitable rest, written by the Captain before his Hermes aircraft G-ALDJ crashed at Blackbushe on 5th Nov 1956 may have influenced Parliament to introduce Flight Time Limitations in the U.K.
( I was required to have a medical if I exceeded 125 flying hours in a month. If fit, some said that I could do a further 125 hours...!)
Two Captains, two Flight Engineers, one First Officer, one Radio Officer and two Bunks were now required for a "Heavy Crew" who could, with Captain's discretion, be On Duty for 24 hours, but must be Scheduled for 16 or less, IIRC.
( Our Hermes had de-rated engines, using 100 octane, so we normally flew at around F/L 10.0 with the cabin pressurised to 2 or 3,000 ft. raising the cabin altitude for Nairobi.)
