When you read about this incident it's very easy to think "idiots" and "I wouldn't do that", it is a natural human reaction.
Then one day everything happens all of a sudden and you have made a mistake which potentially could have been disastrous, and now you are thinking "how the hell did I do that".
Serafim,
It may well be an easy airport but more often and not that leads pilots to being a little conceited and concentrate less.
