A viewing terrace on top of the terminal at BHX would have been great but far too down the line now for that to be added - and I guess a perfect place to aim your Kalazynkov.....but most major European airports have viewing terraces (ZRH and VIE are both excellent with no pesky fences in the way either) so why not UK???? We will just have to make do with Sheldon Country Park, which isn't so bad for photography......
