As per the Westjet near crash into the sea at St. Maarten, and again here the crew made a GA then flew the same approach again and succeeded. I've wondered & asked in both cases what they did differently the 2nd time. By knowing that we might learn, from them, how they screwed up the 1st time.
I read somewhere, I think, that AC's 2nd approach was via a straight in ILS; is that correct? If so we may not learn their fundamental mistake, but what the crew can say, without any doubt, is that the picture they saw on the 2nd approach was vastly different from that on the 1st. In which case how can they say they were not lined up on the taxiway for the 1st attempt. If "something didn't look right" on their 1st visual then it sure a heck looked normal on the 2nd, or they wouldn't have landed.
