Quoted:


The fatigue was not from take-offs and landings.  It was from pressureization cycles. Imagine blowing up a ballon and letting the air back out hundreds of times.  Hawaian airlines had this problem because they do many, many, many short hops between the islands.  Thier cycle to total time ratio was(and probably still is)  higher than any other airline.


Take-offs and landing are not a big deal.  Flying skydivers i make a landing every 28 minutes.  when i was crop dusting it varied but the average was about 35 minutes.  A Cessna 152 doing training might make 10 landings in an hour.  lands and take-offs wear on tires and brakes, but they dont cause catastrofic failures like in the hawian airlines incident.
