A Sukhoi superjet 100 is missing

[PEI_3721]

one track - # 606, “The pax of the Sukhoi expected that the PIC was sufficiently highly qualified and competent, to ensure that he could operate a flight from commencement to conclusion, without killing them all. He wasn't, and he did.”

Your conclusions are reasoned with knowledge of the outcome; thus if there was no accident and the flight landed safely, as did the previous one, the inference is that the PIC was qualified and proficient. So what changed between flights?

Your weak understanding of attitude is perhaps a reflection that other people are prepared to consider different situational viewpoints and alternative theories of human behaviour.
A broad spectrum of industry now recognises these alternatives as a means to progress safety, and whilst they are not a complete answer, or even provable theories, they do generate opportunity to think about issues and perhaps reflect on how some aspects might apply to themselves or be applied in their operations.
