BBC interview about the sound mirror in Redcar: “In 1916 it was sitting in open farm land. Since then a modern housing estate has grown up around it. The concrete structure has not always been treated well. When it stopped being used to detect German raids a farmer used it as a spot to store manure. There have been problems with bike enthusiasts using it as a ramp to practice their stunts.” Release date: 22 January 2014.
Perusing a 1963 Ordnance Survey map, I noticed a long-gone bit of railway which I’d never noticed before, running off the Middlesbrough – Saltburn line at Ryehill Farm between Redcar and Marske. A bit of Googling finds references to Marske aerodrome, complete with photos of the sound mirror from 1983.
