Not widely known is GATCOs assistance, many years ago, to a Rumanian Controller. A BA pilot contacted GATCO London Region and told them about a Rumanian ATCO who was ill with what had been diagnosed as calcification of the brain. As this was before Rumainia became part of the EU, little in the way of medical care was available, so GATCO got (I think) Turkish Airlines to fly him to London and arranged for him to see a specialist. The specialist found he had epilepsy. GATCO arranged for him to be supplied with several months worth of drugs to combat this.
While he was here, he proudly bought himself a new tie, something which was impossible for him in Rumania as it would have cost him a month's salary!
