After several tries I managed to download the report and read it. An extremely thorough report but perhaps overly detailed in places.
I know this has been mentioned before, but what I found staggering was that this was an exact repeat, with a more unfortunate outcome, of an earlier mistake at the Bravo/Mike intersection, by the same airline!
How come that one fell through the cracks at BA?
I24, who is to say that ONLY BA had had the problem previously?
You might find that it was BECAUSE of the comprehensive nature of BA's ASR system that they were able to search for previous issues at JNB and found it.
iirc from reading report, the JNB authorities had no trace of it.
If the local authorities had no trace of the previous BA incident, how many other previous incidents at that intersection have they 'conveniently' 'no recollection' of from other airlines?
Remember also that local operators in and out all the time have much better local knowledge, the true test of an airport layout and procedures and deficiencies is gained from irregular users.
Just a countering view ....
