In Part 4, the birth of 6 OTU turned Sutton Bridge into a fast-paced training hub turning skilled pilots into front-line fighters. Operating Hurricanes, Battles, and Gladiators despite shortages and harsh Fen weather, the unit trained British and foreign recruits under tight schedules and high pressure. Success came at a cost, with accidents and fatalities a constant reminder of the dangers faced even before reaching combat, underscoring Sutton Bridge’s vital role in preparing airmen for the Second World War.

In Part 5, the war expands, the need for pilots increases and the dangers become evermore present.

1941: The Expanding War

Whilst the threat of invasion had subsided by the end of 1941, attacks from German bombers were never far from the minds of those in command. With Sutton Bridge being one of the largest training airfields certainly in Lincolnshire and perhaps across England, it was rarely devoid of attention from the Luftwaffe.

As we have seen, few of these attacks caused little damage, the Q site taking more substantial hits than the airfield. However, attacks did occur, and the loss of a Hampden on 13th May 1941, was among one of the more serious ones.

On each of these bombing occasions fighters were scrambled from Sutton Bridge with little or no success in shooting down the enemy aircraft, but one, a JU 88 of 4./NJG 2, was brought down with the crew being killed. One of those onboard was recovered and it is he, Unteroffizier Heinz Schulz, who is laid to to rest among the sixty graves in St. Matthew’s. Some sources credit a Sutton Bridge Hurricane with the demise of the JU 88, whilst others say it was a night fighter from 25 Sqn at Wittering.

The Air Ministry then decided that with the threat of attack still  present, those airfields nearest the continent would have to be moved, and with enemy bomber formations attacking across East Anglia, Sutton Bridge was seen as one needing such a move.  As a result, contingency plans were put in place to accommodate this and 56 OTU was earmarked to move to Hawarden. However, the move never materialised, and the OTU remained firmly where they were – at least for now.

An International Gathering

The influx of American volunteers was only part of a much wider story as Sutton Bridge became a melting pot of Allied airmen. Norwegians, French, Polish, Canadians, Indians, New Zealanders and Australians all came here to learn the trade of aerial warfare. Many of the continental pilots had left their own homes when they fell to the Germans, escaping to England where they joined the RAF to fight another day. Others simply answered the call to join up and fight against the Nazis.

One such pilot was Indian born P.O. Mahinder Pujji who would go on to serve with great distinction after answering an advert in India, for recruits to join the Royal Air Force.

Mahinder arrived in the UK in August 1940, and by the October  he had received the King’s Commission. His journey to war was similar to many others, with his initial training being undertaken at RAF Uxbridge before he transferred to No. 9 Advanced Unit at RAF Hullavington. It was here that he joined the first group of Indian pilots selected for the Volunteer Reserve Commission. Out of twenty-four trainees, eighteen qualified, with six – including Pujji – going on to become fighter pilots.

After receiving his Wings on 16th April 1941 he was posted here to 56 OTU and Sutton Bridge. Training alongside other pilots he completed his course and was sent to RAF Martlesham Heath and his first frontline squadron 43 Sqn. After only a short period he transferred again, this time to RAF Kenley and 258 Sqn.

Despite suffering several crashes Mahinder would survive the war, achieving two ‘kills’ and three ‘damaged’, and rose to Squadron Leader. His career spanned three theatres of war – a remarkable journey that began on the flat fenland runways of Sutton Bridge.

Crowded Skies, Growing Dangers

This continual flow of airmen through the airfield meant that the numbers on roll were increasing steadily, and to match that, by May 1941, the number of aircraft available at Sutton Bridge had also steadily but substantially increased. 56 OTU now able to operate some seventy serviceable Hurricanes.

For some, the cold and damp British weather of 1941 was a far cry from home, and fog often caught the unwary out. The idiosyncrasies of the Hurricane also took a little getting use to. On October 20th 1941, P.O. Norman Choppen lost power and crashed into the ground after he had entered a shallow dive, possibly with the idea of bringing the Hurricane down to land.  Ten days later, three more aircraft were severely damaged when P.O. McKillop, Sgt. Zadworthy and Sgt. Johnson all landed breaking the undercarriages off of their Hurricanes. Along with four deaths and other accidents, the period from early October to mid November was the most costly in human terms.

1942: Transition and Advanced Training

The transition between 1941 and 1942 saw little change and little in the way of drama at Sutton Bridge. But the beginning of the new year was marred by yet another serious collision in which the crews of two aircraft were killed. However, these were not two fighters, but a Hurricane from Sutton Bridge and a Stirling based at Oakington and 7 Squadron.

On January 17th, 1942 Stirling W7467, piloted by Flt. Sgt. R.W. Taylor was out on a training mission when it was the recipient of an unauthorised ‘attack’ from Hurricane V6865 from the OTU at Sutton Bridge. In the attack, Pilot Officer Derek Browne, aged just 19, made several high speed passes at the Stirling as it headed home. On the last pass, Browne misjudged the distance between himself and the Stirling and rammed the bomber’s fuselage.

The eight crew of the bomber, had attempted to warn Browne off by firing their guns toward the Hurricane, but this failed to deter Browne from his dangerous activities and the ultimate and tragic sacrifice was paid.

The Stirling, being over the soft soil at Haddenham Drain (about 1.5 miles north of Earith Bridge in Cambridgeshire), plunged some 15 feet into the ground leaving a crater that burned for several days before finally filling with water. The condition of the ground meant that the task of recovering two of the crew’s remains, Sgt. McCarley and Sgt. Mankelow was impossible and they remain there to this day. *¹⁵

Changes were afoot – The Central Gunnery School arrives at Sutton Bridge

By March, further changes were afoot and 56 OTU was ordered north to RAF Tealing. Some estimates have the number of pilots passing through here at this point as high as 1,000, many of whom went on to fight in Britain’s darkest hour – the Battle of Britain.

The change of ownership at Sutton Bridge brought with it the Central Gunnery School (CGS), an organisation first established at RAF Warmwell on 6th November 1939. Its role was to provide advanced training for gunnery instructors, covering both fighter gunnery – through the Pilot Gunnery Instructor Wing – and bomber gunnery, via the Gunnery Leader Wing. In essence, the CGS was designed to “train the trainers”, developing specialists who would then return to operational units and pass on their expertise to their own gunners.

Just before the CGS arrived, Sutton Bridge had already experienced a brief period of instructor training with the arrival of No. 2 Flying Instructors’ School (Advanced). Re-formed at RAF Montrose in January 1942, No. 2 FIS (Advanced) provided advanced courses for experienced pilots preparing to become instructors. By March that year the unit had moved to Sutton Bridge, but its independent life was short-lived. On 28th March 1942 it was absorbed into the newly established CGS, which officially transferred from Chelveston to Sutton Bridge on 1st April 1942, the anniversary of the RAF’s formation.

From that point on, the CGS became synonymous with Sutton Bridge, remaining the station’s longest-serving wartime unit. Its dual structure meant that both fighter and bomber gunnery specialists were trained side by side, bringing a wide variety of aircraft to the airfield. Wellingtons, Hampdens, Spitfires and Mustangs all became familiar sights in the skies over the Wash as instructor after instructor refined their skills.

The CGS’s arrival also meant the departure of the longstanding 1489 Target Towing Flight (TT) who had used both the Henly and Lysander as target tugs. With the CGS utilising the range at Holbeach much more along with their own target tugs, the TT Flight were seen as surplus to requirements and transferred out to RAF Matlaske on the North Norfolk coast.

More changes at the Top

Taking up a new post at the CGS, Chief Instructor Sqn. Ldr. Allan Wright, arrived in a Hampden flown by Flt. Lt. Claude Mandeville. He would join Wing Commander Adolf ‘Sailor‘ Malan DSO. DFC. who between them would take charge of the unit  knocking it into shape as quickly as possible. Above them, was the newly appointed and formidable Station Commander Grp. Capt. Claud Hilton Keith who had been told by the AOC that this command was “dirty, unhappy and inefficient.”*¹⁶

Keith would run the CGS in a much more professional manner than had been done before, providing expert training to those who had already achieved operational experience and had proven themselves in air gunnery. To him, it was a privilege to attend the CGS, and standards were set very high.

With courses running for both bomber gunners and fighter pilots, one would be used to ‘attack’ the other whilst cine film recordings in both aircraft were made for later analysis. This proved a useful tool that kept pilots, gunners and much needed aircraft out of relative harm’s way.

The CGS’s ever increasing thirst for quality instructors led to the arrival of Flt. Lt. Richard A.D. Trevor-Roper DFC, DFM in August 1943. Roper was just short of two tours in bombers, when he was drafted into 617 Sqn and the tail end of Guy Gibson’s Lancaster on the famous Dams raid. He brought a wealth of experience and knowledge to the courses at Sutton Bridge which he shared with those he instructed before being eventually posted back to an operational unit.

When Arthur Harris ordered the first of the 1,000 bomber raids, it was an all out effort to get every bomber available in to the air and over Germany. Sutton Bridge and the CGS played their part getting three war-weary time-expired Wellingtons into the air. Each of these bombers flew to RAF Feltwell, where they joined the resident 75 Sqn for operations to Koln. Mainly crewed and maintained by CGS personnel, the Wellingtons included a MK.1A, an aircraft that had long since seen its day, and should have been scrapped, or at least reduced to lesser duties. But determined to do their part, the crew took off from Feltwell and set off toward Germany.

After departure at 23:57 on May 30th, the bomber was not heard from again, and was subsequently found to have been shot down by a night fighter over Klarenbeek in Holland. All but one of the crew on board were killed in the attack, the survivor, Flt. Sgt. G. J. Waddington-Allwright, being taken prisoner and incarcerated as a POW.

The two sections of the CGS (fighter and bomber wings) were initially operating separately, the fighter wing being brought down from Wittering to join the bomber wing at Sutton Bridge in April 1942. With them, came Spitfires, so many in fact, that they quickly lost their ‘head turning’ appeal to both pilots and locals alike. One of these aircraft, P7350, had served with 603 Sqn during the Battle of Britain. After being shot down, repaired and returned to service on more than one occasion, it ended up starring in the 1968 film “Battle of Britain” before heading off to the Battle of Britain Memorial Flight at RAF Coningsby where it continues to fly today. It remains the only air worthy example of its type that actually flew and fought in the Battle in 1940.

Rocket-Firing Hurricane Trials

Another important milestone in the history of Sutton Bridge was the testing of rocket firing Hurricanes as developed by the Aircraft and Armament Experimental Establishment at Boscombe Down. Hurricanes fitted with rocket projectiles used the range at Holbeach whilst being temporarily based at Sutton Bridge. One of these Hurricanes (of which there were initially two) was flown by Wg. Cdr. Albert F. Bennet. Bennet flew Z2415 to Sutton Bridge where he began trials firing the 3-inch projectiles at targets in the Wash. On his second day of flying, July 1st, 1942, the Hurricane, for unknown reasons, suddenly exploded over the village  killing 29 year-old Bennet in the process. Debris from the explosion was scatted over a wide area and two civilians on the ground were also injured. Bennet was later taken to Brookwood Cemetery where he is buried in plot 24. B. 13. *¹⁷

By 1941 Sutton Bridge had grown into a bustling hub of Allied air training, hosting a mix of British, European, Commonwealth, and American pilots. The airfield remained under constant threat from Luftwaffe raids, while crowded skies and inexperienced trainees made accidents a grim reality. In 1942, the focus shifted from front-line pilot training to advanced gunnery instruction with the arrival of the Central Gunnery School. Fighter and bomber crews honed their skills in Spitfires, Wellingtons, and Hampdens, while innovative experiments, including rocket-firing Hurricanes, highlighted Sutton Bridge’s role at the cutting edge of aerial warfare. Despite progress, the dangers were ever-present, with both trainees and experienced instructors paying the ultimate price.
