And then there was Coningsby, standard tower, radio room on ground floor, approach above and local on top. Ops HQ scabbed on one side with Met below and GRSF round the back.
Then, doing some maintenance, it was discovered the Approach windows had simply been filled in with a single layer brick infill - no structural strength and no load bearing for the concrete built local above.
Given that some airfields had remote towers, Cottesmore, Finningley and Dishford amongst others, I wonder why others were sited in the main target area.
