The concept of anyone outside the broadcasting industry having access to a video recorder to beam programmes into a school was rather revolutionary in 1972.

This TV series only exists nowadays as a black-and-white film recording. The color video tape copy was lost many years ago at a time when it was common to reuse video tape once it had been broadcast.

According to the Ordnance Survey map which Forrester and Jessie Ruggles use in Tightrope: Episode #1.8 (1972), Redlow and the air base are somewhere south-east of Grantham in Lincolnshire; Jessie points to the village of Bourne and refers to it as "the village centre".

Forrester: I have a message for you. How well do you know your staff? Who and what are they? Can you trust them? I am the Voice of Truth.
