Speedbird London helped me out of a few scrapes back in the '70s whilst working the old "Foxtrot Foxtrot" flight numbers, especially on the knackered old Britannias. It was always a pleasant surprise to find that an HF set worked and an even greater pleasure to talk to a fellow Brit from the depths of darkest Africa.
Many thanks for a job well done and very best wishes to you all for the future.
