1) 57 years old former fighter pilot who had been a commercial airline pilot since leaving the US Air Force in 1980. He is also a safety expert and a glider pilot [7]. See also Appendix B. 'I was sure I could do it'. 'The entire life up to this moment was a preparation for this moment'. 'I am not just a pilot of that flight. I am also a pilot who has flown for 43 years…'

2) Probability of human non-failure in normal flight conditions is assumed to be 100%

3) The formula would have to be used to evaluate the probability of non-failure in the case of a pilot of ordinary skills. The computed numbers are shown in parentheses.

The computed numbers show that such a pilot would definitely fail in the off-normal situation in question
