In my 20 years, in several airlines, a windshear warning (not caution) has been a compulsory go around, unless of course, there is an emergency. I am making an assumption here that they (EK), after 2 go-arounds no longer thought they might land with less than final reserve, they knew, as such a Mayday was called. Am I missing something here?
Did they make it to MAN? Did they take out a few tower blocks near BHX?
