A device found on land being developed for the Northern Distributor Road was likely to have been planted by British forces in preparation for a German invasion.

Wreckage of Mustang fighter plane found on NDR site

The wreckage of a crashed American fighter plane has been one of the most fascinating artefacts discovered along the NDR route.

On April 22, 1945, First Lt Robert C Young lost control of his P-51D Mustang while attempting to perform a slow roll during an aerobatic display.

His plane, Ellie May, was said to have exploded on impact at Gazebo Farm to the west of New Rackheath.

Last month, archaeologists discovered the wreckage of the aircraft while working at the site ahead of work on the NDR.

Anthony Haskins, project officer from Oxford Archaeology East, said the pilot had only clocked up 37 hours in the Mustang before the crash.

He said: “He was on the way back from a training exercise, but at the same time at Rackheath airfield there was an air display celebrating the 200th successful mission for the 467th Bomb Group.

“Robert Young turned up, buzzed the airfield and control tower and attempted to carry out a barrel role at low altitude, which didn’t come off.

“He basically inverted [the Mustang] and because he did not get enough airspeed, the plane stalled.”

First Lt Young had previously been a B-24 co-pilot of the 93rd Bomber Group, but was given the opportunity to fly the Mustang with the 479th Fighter Group, based at Wattisham in Suffolk.

He had been returning from gunnery training over The Wash when he decided uninvited to take part in the aerobatic display, which had been put on by the 56th Fighter Group.

After he lost control, his plane exploded into the ground between the gymnasium and 791st Squadron quarters.

Remains found at the site last month include a gun camera ID tag, .50 calibre ammunition and the plane’s propeller spinner.

Chris Collins, who runs the 467th Bomb Group Facebook page and researched the crash, said: “In terms of quantity of wreckage found it is a relatively small amount considering the size of aircraft, but considering the violence of the impact and following recovery efforts in 1945 this is hardly surprising.”

First Lt Young was buried at the American military cemetery in Madingley, Cambridge.

The Mk 1 chemical mine was spotted by contractors on Tuesday morning during a search for unexploded devices around the former RAF Horsham St Faith airfield.

Experts believe the object was buried during the Second World War as an “area denial” device and could have once contained a quantity of mustard gas or phosphorous.

Its discovery on land off Bullock Hill resulted in a 200m police cordon around the site as bomb disposal experts from the Royal Logistics Corps examined the object.

Ten people were also checked over by paramedics at the scene to ensure they had not been affected by the contents of the device.

A spokesman for Norfolk County Council said: “The item found was an empty Mk 1 chemical mine, initially produced in 1914, but adapted for defensive purposes which is probably why it was in that location.

“It may have contained incendiary or illumination fill, but when found it had already been damaged, probably, by ploughing, and any contents had long since dissipated.

“However, it potentially still contained an explosive expulsion charge, hence the requirement for bomb disposal.”

The mine was found by specialist contractors 6 Alpha Associates, which has been employed by the council to check for unexploded ordnance near the NDR.

Similar checks have already been carried out near RAF Rackheath, where the remains of a crashed P-51D Mustang were discovered.

A council spokesman said the mine’s discovery would not impact on the delivery of the 12.5-mile route, which runs from the Postwick junction of the A47 to the A1067 at Taverham.

Robin Rickard, programme manager from 6 Alpha Associates, said the mine was one of many types of anti-invasion devices installed along coastal airfields during the war.

He said: “It would have been initiated by a trip wire, which would have basically thrown mustard (gas) upwards and outwards, so anyone in the vicinity would have got a lungful.

“Chemical weapons pose a very different hazard to conventional unexploded ordnance, and detonation must be avoided in order to

prevent the discharge of harmful contents.”

Mr Rickard said other anti-invasion devices included burying pipes filled with nitroglycerin underneath airfields, which could then be detonated to render them useless.

But he stressed there was no indication that such methods had been used at RAF Horsham St Faith.

After the mine was discovered using metal detectors, it was removed by a bomb disposal team based in Colchester.

An army spokesman said the device was packaged, sealed and removed for “safe disposal”.
