Goddess Hartley, a 51-year-old warehouse caretaker and her partner, Graham Holden, a 54-year-old lorry driver, was walking their dog Bonnie on a beach in the town of Cleethorps on Monday when they spotted the plane.
Hartley told CNN the couple did not understand what the wreckage was at first and spent 45 minutes searching and photographing it before locating it.
After returning to the country to begin research, they discovered the World War II-era aircraft.
The Royal Air Force (RAF) museum in Britain has confirmed to CNN that they believe the aircraft will be believed to be from Bristol Boufighter TF.X, 254 Squadron RAF, with the aircraft’s serial number JM333.
Ian Thursk, head of the RAF Museum’s collection, told CNN in a statement that the plane crashed on April 2, 1944, shortly after taking off from North Coates, near Lincolnshire, after both engines failed.
“The crew escaped unharmed,” Thursk added.
Speaking to CNN, Hartley said he was surprised to stumble across the “surprise” rubble as he and his partner had set foot on this side of the beach many times before.
“(I) have never seen this before in my life,” he said.
“We took the dog on its normal walk and suddenly we saw this wreck,” he added. “It was an amazing search.”
“My partner has lived in Cleethorpes for 30 years and she has walked the same path (all the time) and never come before.”
He said that before the unique discovery he was “not at all interested in history” but now he would like to know more about those who flew the plane.
However, people have been warned not to look for the wreckage as there is a risk of unexpected tides on Cleetops beach.
“We have also received reports that it is already covering with sand again.”
The definition has been modified to reflect this story that the craft is a pilot aircraft.
