Many thanks to SWLing Post contributor, David (G4EDR), who writes:

Looking forward to this documentary TV programme tonight. Looks like it will be about the BBC WS during the cold war.

Thanks for the tip, David!

Readers, my post is a bit late–David sent this two days ago. Still, the program is on the BBC website for a few more weeks, however it is very much geo-blocked so you’ll need a work-around if viewing from outside the UK.
