Blister hangar used here as a free training space where different equipment could be laid out for air crew training.

There were WAAF's in WW1 but in WW2 they were brought into the RAF in greater numbers to run the camps, drive, mechanics (air & vehicle), radar, ops room, etc, etc.

The derelict site on the right may have been another communal site. The building is not WW2 but both sides of the gate posts are these concrete blocks like anti-tank blocks.

History :
RAF Tholthorpe started life around 1930 as a grass field for the use of RAF Linton-on-Oise.
1940 it was used by No's 51 & 58 Sqn's Whitley's.

There is a good line drawing of a turret trainer in Paul Francis book 'British Military Airfield Architecture' page 151. It shows a concave screen which an image was directed on and a form of scaffolding tower with several levels, one with a dummy turret and another for a controller, there was also a power unit.

50Ft perimeter track.
An 'A' class airfield as this one became, had a perimeter track 50ft wide connecting all the runways of 150ft with 36 aircraft dispersals.
History :
In the early 40's
Tholthorpe was a grass field which in wet weather gets very boggy and modern bombers starting to get heavier and bigger. A new airfield was needed. So a complete re-vamp to turn Tholthorpe into an 'A' class bomber station took place from January 1941 to June 1943. Three hangars (2xT2 & 1 B1), a new watch office, a full bomb store & a full dispersed accommodation.
The circular perimeter track was the original airfield and later the runways were added and the main one was extended.
Early 'A' class had around 36 circular dispersals, these were very effective in keeping the aircraft dispersed around the perimeter and also a good firm base for the plane to sit. But God forbid you drop a wheel off the concrete onto the mud or grass and it was a heck of a job to get it back on firm ground.
The second type of dispersal that came into use after 1942 was the Scissor or Spectacle type. The circular pans damaged aircraft doing a tight 360deg turn, whereas with the spectacle they could drive in and continue out without turning. Tholthorpe had at least four (possibly more) spectacle and the rest circular.
Halifax on its dispersal. There would be a ground crew hut and latrines with several dispersals per hut where the ground crews of those aircraft, could rest keep warm and store things and also use the toilet.

Air photo.
With the technical site in the S/E side and S the old bomb store, S/W the later bomb store. N/W a B1 repair hangar. N/E another T2 hangar and later Spectical dispersals.
When opened it was an early grass airfield, a small perimeter track able to take vehicles around the landing ground. After the winter of 1940 when no flying could take place due to water logging, three 150ft wide runways were laid and the perimeter track increased to 50ft width. Then the main runway was extended as heavy bombers needed more length and the large bomb store added and it became a full 'A' Class bomber station.
The original airfield layout.

Stage two was to upgrade the perimeter and add three runways.

Night Flying Equipment Store 12411/41.
Night flying equipment stores held all the goose neck flairs, beacons and any other equipment used for night landings and take off’s. An airfield may not have had lighting or if they did and the electricity failed the oil lamps could be put out. Fine on a small airfield but as here a very long runway of over a mile to put out all the lamps.
Goose neck flairs, paraffin filled heavy (like watering cans) with a wick in the spout, then lit by a match it would burn for quite q long time.
Goose neck flair at work.
Chance light a sort of searchlight that could be deployed at the end of a runway and the light pointed down its length. Just another aid to help a pilot land in the dark.

Armoury & Armoury Maintenance 9882/42.
Built in Temporary Brick (half brick) which was a cheaper and quicker construction than the pre war designs. The windows were standard Crittal steel windows and can still be bought today. The method of building with piers along the sides where trusses lay on for strength goes back to WW1 designs of military hutting and can be seen at RAF Duxford around the hangars.

The later control tower.
The name Watch Office changed in the mid 40's to control tower. This was due to two reasons, one - only a watch was kept on an airfield and their pilots could land and take off at almost their own discretion. Two - by 1942 onwards many more aircraft were being used at one time and a form of control was needed to make for a safe and smoother running of the airfield. So the Control Tower was named & designed and placed in a position where it could see ALL the airfield.

Aircraft tie down.
Bomber aircraft are quite heavy, but a wind can quickly enable them to fly when just stood on an open airfield. So great lumps of concrete were set into the dispersals with a large steel bar inserted. A cable/strop would be attached to the aircraft and held down.
Circular aircraft dispersal (frying pan or just pan) had several of these set into their concrete base and planes could be tied firmly down in high winds.
