<<PS: IF this incident was at ALL related to the outdated idea of using QFE for landing...is it not about time that BA abandoned this rather backward idea?>>
Your "worldwide" experience is obviously not as great as you make out. Yes, BA do use QFE into certain airfields where it is state procedure... as do all other airlines (to my knowledge). QNH remains the standard at most airfields. The problem is that EGPWS relies on QNH being set to match aircraft altitude with terrain database...
There is always scope for common sense. My disagreement with your line of attack here is that a GPWS warning, if genuine, might require immediate action to avoid the terrain - there is not time to have a full 2 or 2 way CRM discussion in "what do you think chaps - shall we ignore it?". So a "Pull Up GA" should be flown, since all expect that...
Subsequent to this, we can now hold the CRM discussion, review the charts, position, and decide if it was genuine, a possible GPWS fault etc. Now common sense may dictate "ignoring" a further warning depending on the outcome of the above discussion.
