I prostrate myself before Heathrow Director´s greater knowledge
However wouldn´t safe operations without radar depend on all ATC people being able to understand English? And the Ministry of Defence and the Air Force working in good faith and not bullying civilian staff into hiding problems?
The issues involved are more than just the absence of radar. When I have time I´ll post some stuff from the - respectable - press and summary translations.
Again, I recognise that I am not an an expert, everything I say here may be wrong, the Air Force may be a splendid bunch of chaps selflessly dedicated to keeping us all safe in the air, Enrique Piñeyro may be a dangerous fantasist etc etc
