The hangars at the top were typical solid brick built RAF hangers just as shown in the picture of the aircraft on the transporter.
The hangar in the picture was known at Henlow as 'The Pickle Factory'. The story was that it had been built back to front so that the doors faced away from the airfield and that left the person responsible for its construction in a 'pickle'. It has now been demolished.
I saw the TSR-2 sitting on its wheels but by the time I had been to work and then bought some film, it was in pieces on the trailer. The second trailer carrying the wing had already left.
