Engineering series 2: The Concorde


In the second part this engineering series we will take a closer look at the supersonic passenger airliner Concorde, which was developed in the mid-20th century in France and Great Britain with much public attention.

As an amateur radio operator, this place with its small airfield, eye-catching antennae, and disused radar-facilities on the peak aroused my interest to learn more about its history.
