I’m afraid you think wrong - I can assure you that they did. I was one of the QFI instructors involved and somewhere I still have my RAF logbook entries and the course photos. It was carried out under the “Aid to the Civil Power” training scheme. I also flew an RAF aircraft with a police observer who carried a police radio and was in air/ground contact with local traffic police, part of an experiment controlling a rolling road block for a major event.
