The School was located approximately where the frieght sheds to the west of the terminal are today. At a guess I would say approximately at the southern end of the FedEx area.
There was a significant amount of land fill when the new terminal/cargo area was constructed, so no physical trace remains today.
Our historians/enthusiasts group (Air-Britain Stansted ) used to meet in the lecture theatre of the School during the late 60's /early 70's and we were fortunate to be given access to some of the training films and materials used. I wonder what happened to all of those rolls of cine film?
