An article about the Speedbird London HF service:-

As I remember it, the men and women who were the radio operators were situated on the 4th floor in the north east corner of TBA at Heathrow. I have used Speedbird London from both ends, as it were - down route in the air and on the ground, and also as a manager trying to help crews with problems in many varied places on the globe. I fully endorse the many compliments that have been paid by users on this thread to those who gave such an excellent service, day and night, and at all times of the day.
Aerial-Bender, either you or one of your colleagues should write a book about your experiences, I am sure there are many tales to tell.
Many thanks to you all.
