At the beginning of the war the Air Ministry searched out sites for brand new aerodromes, this large area of
meadow called Tholthorpe
Moor that is located Northwest of the city of
York. The
aerodrome in late 1940 with
a grass field was a satellite
airfield for the operational
airfield at Linton-on-Ouse.
The winter operations in 1940/41
proved the grass field to be
unsuitable for ‘Whitley’ aircraft,
and in late 1941 work
commenced to construct concrete runways. Runway 10/28 was 6,000 feet
in length, runway 05/24 and runway 16/34 were both 4,200 feet long.
After completion of the works to bring the airfield up to RAF Class ‘A’ standard, in the
summer of 1942.
RAF
Tholthorpe remained as a satellite/dispersal airfield for
aircraft from the main station at Linton-on-Ouse.
In June of 1943, the airfield was allocated to the new No. 6 (RCAF) Group that had
been formed in October 1942. No. 434 Squadron RCAF was then formed at Tholthorpe
in June, 1943, flying ‘Halifax’ B.Mk.V aircraft, and in May, 1944 B.Mk.III ‘Halifax’.
In July, 1943 No. 431 ‘Iroquois’ Squadron RCAF transferred in to Tholthorpe with
‘Halifax’ B.Mk.III aircraft.
In August of 1943, both No. 431 and No. 434 Squadrons began a series of operations to
bomb targets in northern Italy, and four months later - in December, 1943 - those two
Squadrons were transferred to Air RAF Croft.
In December 1943, RCAF Squadrons No. 420 and No. 425 - both returned from five
months service in Tunisia with No. 331 RCAF Wing and arrived at Tholthorpe to
convert from ‘Wellington’ to ‘Halifax’ B.Mk.III aircraft. The two Squadrons flew their first
missions from Tholthorpe in February, 1944, and remained on the station on
operations until their last missions in April, 1945.
No. 420 and No. 425 Squadrons RCAF converted to ‘Lancaster’ B.Mk.X aircraft in May
of 1945, but never flew the aircraft on operations. They did fly the Lancasters back to
Canada in June, 1945.
The RAF did not activate Tholthorpe at the end of the war, and for
a few years the airfield was used for private flying, with the runways and hangars in fair
condition. But by the 1980’s the hangars and most buildings had been removed, and the
runways began to disintegrate.
Farming activities have now taken over the airfield, and light industry has taken over the
technical site. The 1943 control tower is now a private home.

I was invited by a man that worked in this Chicken farm. (sorry cannot remember his name).
We then drove around the airfield. Its nice when this happens, he knew nothing of the airfield and what had been in the WAAF site. The chicken farm was a restricted area due to any contamination and I only visited the entrance area.
This is a plan of the communal and living sites. Most living sites are for men, Sites 11 & 12 are for W.A.A.F.'s. Site 3 is the old communal and site 4 the added new communal site. Site 14 is he Sewage site and Site No.2 admin.

81 - Control Tower - TB - 343/43.
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 at 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.

50ft perimeter track.
An 'A' class airfield as this one became, had a perimeter track 50ft wide connecting all the runways of 150f wide, with 36 heavy bomber aircraft dispersals.
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.

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 placed 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.

Seagull trenches were an early open pillbox defence to protect the bomb storage area I think.
Tholthorpe Home Guard. Initially local Home Guard units were used to guard airfields, but as the army increased in size, the county regiments (in training) were used and later the RAF Regiment took over.

153 - Fuzing Point (Ultra Heavy) - N - 7900/42.
In February 1924 after all the tests had been carried out, it was decided to go ahead with the designs of General Purpose Bombs. The idea of the General Purpose Bomb was that it should be easy to produce in large numbers and give a good percentage of efficiency against every type of target, obviously unlike a specialist bomb it would never give 100% effect against any target. It was decided to have both tail and nose fuzing to prevent break up of the bomb on a hard target and allow penetration of softer targets. Unfortunately this meant that the bomb would have practically no anti-personnel effect on soft targets in the open - this lead to the development of smaller fragmentation bombs such as the 20lbF bomb.

153 - Fuzing Point (Ultra Heavy) - N - 7900/42.
Bomb Pistols (e.g., No. 28): Simple firing pins that initiated the main charge upon impact; they contained no explosive themselves. Fuze No. 42 (Mark IV): Featured a time-delay capsule, used on flares and cluster munitions, and even adapted for the Upkeep bouncing bomb.

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.
