Krystal,
Jonathon Falconer's "Bomber Airfields of WW2" lists Bellman and Blister hangars only at Honiley, both of which were corrugated tin/steel affairs so it's not one of those. Nothing in the English Heritage "Cold War" book.
There was an awful lot of R&D going on around Coventry in the 50s involving aviaton and rockets (Rolls Royce at Ansty for example). My dad lived there in the 50s, I'll ask him if he knows anything about it.
If you find out in the meantime could you post the answer please ? You've got me intrigued.
Ta, Stuart.
