Mr Stafford was a historical advisor for Microsoft on combat flight simulators. He was approached by Microsoft after meeting an American pilot at a Warbirds Over Wanaka air show in 1998.
"They wanted to get the language and things right."
As part of that role he wrote a series of six articles about his wartime experience - from training, to early missions, and through the end of the war - and was flown to the United States twice.
While his stories are nearly always accounts of war, Mr Stafford has also written about hunting.
One of his stories, featuring wife Edith, was published in a hunting magazine.
He also writes for the Warbirds Over Wanaka booklets.
Mr Stafford met American author Ernest Hemingway while in Europe during World War II.
