Your direction, not your intention, leads to your destination
While management of any corporation will always try to cut corners in the name of profit, in this case it appears like simple pilot error.
While i never earned a ticket i have logged 5.5 hours of single engine time and the one thing that was drilled into me head was "altitude is my friend but airspeed is my next breath".
I spent half of my airtime flying laps and running checklist and i was required to know airspeed every time my instructor asked and i was also drilled on stall recovery...nose down..add throttle..until it was just a reflex....when stall warning goes off or the wheel/stick shakes, there are no other options...even at 100ft altitude it is the one move that will save your ass or at least minimized damage.
I am kind of surprised that commercial aircraft could even be stalled, the 'stick shake' they have is computer generated and i have seen vids of military aircraft taking off from a carrier and the control surfaces are moving around faster than any human could move them while they make enough airspeed to actually fly.....ie fly by wire and mostly likely impossible to stall..or at least drop a wing.
As far as pilot fatigue...The moment a pilot steps onto an aircraft it is little more than a mental program, a program that will override fatigue until total exhaustion sets in...and the ability to recognize when the point of exhaustion is beginning...i.e yawning on final, a time when a pilot should be at the highest level of concentration?
In this particular case it seems like basic pilot training was the primary cause, and corporation as a contributing factor...and life will always have contributing factors...
Like a herd of birds in your engines and Sully Sullenberger...lose power on takeoff must be about the scariest thing on the planet.
What did he do? Got the nose down and kept flying...and ya..he did get a bit lucky...but i bet money every move he made was all reflex.....Hell maybe we had the same instructor.
And RIP to all those involved.
