Indeed .. I was working in that neck of the woods at the time and got a fair bit of feedback on the 76 incident ..... talk about a close call .... of very great importance was the particular airline's safety philosophy and culture ... the crew made a detailed report and 'fessed up to their own shortcomings .. and the company's response was to get to the core of the causative problems rather than take the easy way out and blame the crew ... a lot of other operations could well follow their lead ... As a result the investigation was extremely in-depth, wide-ranging, and, in the end analysis, very valuable.
I think that we just have to accept that ATC workload and traffic fit in busy places will always leave us with having to accept the occasional high approach ... not a major problem if the pilots have their thinking bits switched on and, if not pushed to silly extremes, is not unduly hazardous. I would suggest that the main aim is to have a bottom line in one's operation ... and don't go outside it ... to decline under circumstances which are not reasonable might cause a little ATC discomfort ... but that's the way it goes from time to time ...
