I like this analysis because it highlights that airliners and their working cultures are the primary cause of these crashes. Quite often, unfortunately, the presenters only point at violations and waive their hands: "why on Earth?" But in reality, personell often skips procedures under the pressure of the management, and this works without consequences. In this Armavia case, the crew had an option to not fly at all, but I suspect, hesitated to delay, expecting being reprimanded (even if unjustly).
