AIUI, that was a new policy implemented after the Germanwings suicide crash, so as to avoid ever having one person alone locked in the cockpit. But you’re right, China may or may not have adopted that policy.
Wiki’s list has been updated to include this flight. It lists it with the color green, meaning possible suicide.
What is it with the Month of March, and specifically the 23rd???
I have seen studies pointing at Springtime as the season where more suicides take place.
The reasons are still being investigated, but environmental factors (that increase during spring and can affect people that travel a lot) like allergens make people already affected by other factors to have a propensity to end it all.
Allergy has been previously linked to suicide [13]. The seasonality of suicide has been shown to co-occur with the seasonal peaks in ambient pollen concentration during spring ( i.e. , tree pollen), summer ( i.e. , grass pollen), and fall ( i.e. , ragweed) [19]. Pollens are aeroallergens and are capable of inducing an allergic inflammatory reaction when they reach the intranasal mucosa of susceptible individuals. The inflammatory reaction induced by aeroallergens involves the production of Th2 cytokines which, in animal models, have been associated with increased anxiety-like behavior, reduced social interaction [51] and aggressive behavior [52] all of which can be considered as endophenotypes for suicidal behavior [53]. Furthermore, the seasonal peak in aeroallergens resulting in the concomitant worsening of allergy symptoms could (via inflammatory mediators of worsening allergy symptoms) potentially worsens depressive symptoms, anxiety and impulsivity in mood disorder patients, resulting in exacerbated risk of suicidal behavior.
Bumping this because Mayday: Air Disaster just released a video on this crash. Mayday: Air Disaster does high quality reenactment-style documentaries.
That seems to be about a completely different crash? Maybe you were looking for this thread:
