Interesting comment in ampclamp's linked article above:
Aksan Giniyatullin, chief executive officers of Tatarstan airlines, which operated the jet, told a news conference: "The lead pilot had never made a second landing attempt under real flight conditions."
I'm not sure that 9 out of 10 successes is any better than 0 out of 1. The idea is to train for 10 out of 10 (or some such) in a simulator before trying out under real flight conditions.
Let's see what the investigation turns up in this regard
