There are a number of people on this site who get quite offended when anyone proffers a possible reason for a reported accident (e.g. Big Red L and Gorilla). Be advised there are many others who contribute to this site who have a lot of experience and can provide valid possibilities for causes to an accident. We have heard that the crew elected to make an approach with a tailwind out of limits to a fairly short runway. Furthermore it was a practice cat II approach (even more restricted tailwind limits), the wind given by the tower is the surface wind (it would be stronger further up the approach) and the crew were not familiar with Liverpool. I think we can make a reasoned conclusion that the crew exercised fairly poor judgement.
Now hit me.
