Henley or High Post?
Hi
looking at the photo that has a link to High Post, and matching it with the original black and white one plus a current aerial view i am certain that the hangar used in the film is High Post, as there is a shed that runs down the left side which has blocked out all but one of the windows, and on the left of the original wartime photograph there is a small building in the distance with a pointed roof, this matches exactly the same position in the aerial photograph
of today.
