Heathrow Harry:
No-one is going to wait for "the official report" for heavens sake - it might be years
On the contrary: everyone will have to wait for the official report. Anyone thinking they can learn from what they BELIEVE to be mistakes is highly likely to be making plenty of mistakes of their own.
...but we need to know what happened and why...
True.
Not true. Your impatience does you no favours, Heathrow Harry in Haste.
I'll bet todays disaster will make a few people think again about approachs in bad conditions - for a while anyway
Why? What sort of extra thinking are you expecting people to do? If conditions are CatI, then CatI approaches are fine. If conditions are CatII, then a CatII approach needs to be made by CatII qualified crew, in a CatII certified aircraft, to a CatII runway. What extra are you proposing?
