Not sure if this has been posted before but it has an interesting piece about RAF Hethel and Lotus. It’s the first item in the programne from 2018.

Fascinating for the history. It includes RAF Bawdsey where the radar systems were developed.
I used to swim and sail in view of Bawdsey Manor in the 50s and passed it for two trips to Ostend in a 18’ yacht in the early 60s. The 350 foot radar masts were still there and could be seen for miles out to sea.
