Paul Koring has written several avaition pieces for the Toronto Globe and Mail's over quite a long time. While he may be better than the average run of popular press writers on aviation, in my opinion he still has a considerable way to go.
One of his earlier pieces on this incident implies severe criticism of the pilots for leaving a crossfeed valve open. Assuming that the checklists call for the crossfeed to be open once the engine is secured (LP and HP shut) and the difficulty of seeing even a heavy leak at night, my opinion is that Koring has taken a position while important facts are still missing. But it was an eloquent article that would appeal to the general public.
