Hmmm.... I understand the problems with the ATC this day but surely the brief before the 2nd approach should have been "in the event of a go-around this time we will divert to our alternate"?????
In the airline I work for we do maximum 2 approaches and then divert (unless exceptional reasons not to). Did they declare a mayday? Or a "fuel emergency" (which is legally not recognised in Europe). Did they make it clear that in the even of a go-around from the 2nd approach they would have to divert?
Yes, sounds like ATC/ airport authorities were not helping here, but surely even if you don't agree with the politics you should bide by the legalities.
