FlyMD - Totally agree. I still stand by my previous post, but even if there is a valid argument for the first GA, the BA ruling which resulted in the second GA (even though I am sure the crew were well aware of the map shift and their true position!) is inexcusable. It resulted in more time messing around in a tight valley and a high workload environment, followed by a landing with a 15kt tailwind......so 30kt higher groundspeed than required. In terms of "safety exposure" this was totally unnecessary.
