Spitfire hunter David Cundall has vowed to continue his search for the iconic fighters in Burma despite his backers pulling out.
The farmer said he remained “very confident” of finding a consignment of the planes in the jungle despite online game company Wargaming withdrawing its support last Friday.
The firm said stories of aircraft buried at the end of the Second World War were just “legend”.
But Mr Cundall insisted the hunt would go on.
“Wargaming came into this for publicity,” he said. “They are not Spitfire enthusiasts at all.
“I have interviewed eight eyewitnesses and I am convinced they are telling the truth. They were all here in the war or just after the war.
"They are all pointing to the same area.
The remaining team – including a local businessman – were now awaiting the arrival of a European company that will conduct a specialist radar search, Mr Cundall said.
In its statement, Wargaming said no surviving witnesses had seen planes being buried and its research in British archives had failed to produce any evidence of the arrival of the aircraft in Burma in the latter months of the war.
