In the same era as the Saudi princes at Cranwell; mid '60s; we also has a Jordanian engineer. In contrast to them, he was as poor as a church mouse. He was a lovely chap who put 100% into everything. There were Sudanese and Pakistanis going through in that period as well.
There were Kenyans going through Nav School in the late '60s. I don't know what they were like professionally, but socially they were stars!
Perhaps my most poignant experience was sitting in the shade of the wing talking to a Sri Lankan who had passed through Halton. We were at an airfield no one has ever heard of in a place that no one would wish to go. We had arrived there on the tide of events and were both a long way from home. It proved that our passing through Trenchard's respective systems; Halton and Cranwell; had left us with much in common.
