Space alien/compound statistical BB shots, and other associated attempts at ignoring occam bore me, so I'll explore the human factors bit some more. One of my more prolific youboober personal acquaintances was taping an episode with his podcasting buddies. One of them brought up the issue of redeye flying (WOCL) on ability to deal with contingencies. I thought that was a legit good point.
A lot of people minimize how fatigue affects the rank and file out there when operating in that window.
UPS 1354 is a good case study on how lack of rest, or lack of personal discipline in circadian management, can impact operations when you need a glovesave.
WB operations on long routes typically are augmented, it's the NB unaugmented crews where this thing gets russian rouletty. Nobody wants to internalize their buzzed-drivers up front may be working on the personal body clock equivalent of a 0.05-0.08% BAC. To say nothing of the fact it's nowhere near the physiological setup they are afforded when that stone simple single engine go-around turnback is given to them once a year on a sim they knew were getting that day in the first place. And they get that IMC in the sim, the fact this happened in CAVU is just insult to injury at this point.
I'm not chucking from the cheap seats on that one. I've flown a /heavy for 15+ hours with us two indentured clowns up front fatigued as all get out. KBAD to the Yukon MOA, all to get killed by Raptors (overkill, a Mig-17 would suffice for that blind duck lol) in 2 seconds flat (morale gauge placared INOP lol), air-refuel, then fight the circadian demons all the way to home plate. WOCL, non-stop, unaugmented, not even party drugs offered. More than 24 hours awake toothbrush to toothbrush; my personal manifestation was a tendency for giddyness/amped up after landing. To date the stupidesh ish I've done in my life, second to marrying my ex. But digressing on all the reasons my username checks again.
Thankfully civilians know better and restrict/augment that nonsense by rule. Problem is employers and employees alike work under perverse economic incentives, and leakers push through the proverbial
DCA line. We don't yet publicly know the 72 hour lookback for this crew, or work conditions of this airline. Not familiar with the work culture bifurcation between Korean LCCs and their flagships, so legit asking if this airline is the sweat shop/Ryan Air of their country.
