But I THINK.... the canberra's were parked in the so called 'Dispersals' and I have seen pictures of them and it looks on the pics they were nearby the tower on the southside of the airflield. These dispersals can still be seen today!
Answer No.1:- Canberra Corner was used as a location reference point in the late 1970's. A number of old Canberra's were parked on a grassed area on the south eastern side of the airfield, in front of II(AC)Squadron and next to the North Circular road, just before you get to the approach lights. I believe they were used for damage repair training.
Answer No.2 The North West Frontier was the name for the unused PAN site (no Hardened Aircraft Shelters (HAS) at that time) located on the North West side of the airfield.
Spooky things used to happen in that area On some night's RAF Police dogs refused to go in this part of the airfield.
