cor...we could have had a mini bash on the ramp!! I was the FO on the Astraeus 73 that day and, as H mentioned, we had no problems at all with GPWS. I understand that the BA problems were caused by map shift triggering a spurious warning, which is still a mandatory Go round.
Having said all that it is quite a spectacular base to final turn, I'm glad I saw it in 50k vis.
