Wow 404, never seen you angry before....
The NY flight is a day flight...I would rather do that 19hr day with 4 crew than a 3 day 111/110 or 135/134 with 3 crew. I won't begin to second guess this guy but I would probably have continued AS LONG AS the other 3 guys were happy to. Flying is about common sense...for those that don't have common sense we have Vol 1 and Vol 2part2.
How much taxi time was there at the end...he might have touched down 30mins earlier adn then been delayed...what does he do then, shut down arm the slides and evacuate?
By the way mr bloggs, I can assure you that 404 is no more management than I am.
I can't recall how many times I have been into discretion as CN/FO in my career here...but I know almost all of them were not 'emergencies'.
