Quote "He had slept for only 3.5 hours in the 24 hours before the flight taking off on March 20."
Unfortunately it would appear to be not just a problem for feeder airlines.
After too many accidents caused by sleepy / sleeping drivers, driving hours in the long-haul trucking industry are now (at least partially) monitored via cameras on overhead gantries and in-truck recorders. Not as simple for the airlines, but it may come to this.
