Heathrow Approach Path

BTW having operated into LHR for over 20 years the ATC pros hercoming up with a lot of "blimey, I didn't know that stuff" - thanks ladies/gents

Which reminds me that we never heard back from the OP - has he been blinded by science or is he just plain ungrateful ?

the holds are moved all over the place, often x miles from the hold with ATC deciding which way to turn

I happened to be looking at FR24 when the Ethiopian 787 got singed - I think there was another incident which closed 09R a short while earlier too; there seemed to be aircraft holding at locations all over the SE - and this before FR24 showed as many aeroplanes as it does now.

treadigraph... Exactly. When it "blows" the fancy book work doesn't cope so then the ATC people fix it themselves.
