Larry Diffley was a legend in Minnesota's aviation community.
His flying skills were considered extraordinary, his people skills top-notch and his business acumen as sharp as they come.
So it was a surprise to friends and family when Diffley died in an airplane crash last week while doing an aerial pipeline survey near Manhattan, Ill. He was 74. He was the only one on board. The cause of the crash is under investigation by the National Transportation Safety Board.
In 1970, along with partner Mark Shough, Diffley took over Bemidji Aviation Services and its fleet of three aircraft and grew it into a regional business with nearly 40 planes today.
"He was a significant player in this market for aviation," said Tom Letson, a first officer for Delta Air Lines who flew for Diffley early in his career. "There's a lot to this guy."
Letson said Bemidji Aviation aircraft flew people, cargo and even firefighting missions to pinpoint hot spots for water bombers.
"When you worked for Larry, you flew everything," Letson said.
Diffley grew up on a small farm in Becida, Minn., a small town near Bemidji. In his early days Diffley lived with his parents and six siblings in a tar-paper house lacking modern-day amenities, said son Tony Diffley.
