Big deal,
During the early years of my career we made up to 13 take off and landings in one day. We also flew DC-9 aircraft into 5,000 ft. runways and circled to land with 1 mile visibility and 400 ft. ceilings.
Sure I ended my career at 43,000 ft. with one or two legs each day.....but it wasn't that way for many years.
Yes...fatigue is a major issue. But 5 legs in one day? Give me a break. What a bunch of crybabies. This is the life of a pilot. Perhaps some would better be suited as University Professors.
