Changes were not that frequent, as I said before - and any changes should have been NOTAMed on the printout given to Collins that morning. They were not.

Fair enough. Why do you hold him in such high esteem? Do you not think he's a bit lite on aviation experience to understand fully what the environment is like?
they had a dispensation to descend as low as 500ft if invited to do so by Mac Central under radar guidance.
Who issued the dispensation?
