With regards to training for high tolerance situations. Places and times where a small error can have large consequences.

Yes you ease into it, the first level of training is done in a safe environment, however as the person gains competence the training moves into the domain in question, the person gains experience at doing the thing in question while being supervised. Or to put it another way.

What? You expect that their first flight through that tight corridor at night should be done alone?

In conclusion, I think it is fine in general that they were doing training on that flight path. However the fact that the both pilot and the trainer erred so badly indicates the need for better low level training and a reevaluation of the need for such a tight flight path in a civilian zone.

Update: unrelated thought, I could not decide if low or high tolerance was the term i wanted, after waffling a bit I went with high tolerance. as that is the correct engineering meaning, but really the term is ambiguous and means the different things in different domains, he has a high tolerance for alcohol means the opposite of he made a high tolerance part.
