The fact that this has not happened for a long, long time says a lot for the skills of those who have flown into there for so long. It can be hard work! Rather than anyone think to criticise those who have been unfortunate today, we should admire those who land regularly in those conditions, after long days and after busy years. Yes, I know there are "the numbers" that you must fly to, but those last minute gusts do not read the same books.
