Two men have died after their glider crashed at an airfield on Queensland's Darling Downs.

The crash happened at the Darling Downs Soaring Club at Bowenville, near Dalby, just after 10:00am on Tuesday.

The pilot, 62-year-old Jeremy Thompson, and his 60-year-old passenger, died after the glider — an ASK21 — crashed into a field near the runway as it was coming in to land.

Mr Thompson, who is an experienced gliding instructor, and his gliding student were treated by paramedics but died at the scene.

Gliding Queensland president Lindsay Mitchell said the glider "inexplicably nosedived".

"He'd been flying a lifetime a very, very experienced glider pilot, very experience powered pilot," he said.

"It's really hit a lot of us."

The pilot's wife was at the airfield and witnessed the crash.

Mr Mitchell said he has known Mr Thompson and his wife for many years.

"We're at a loss to know what happened," he said.

"We are a very small community.

"Jeremy would have been extremely well-known across Australia so it's going to have a major impact.

"It won't stop us flying because we enjoy our sport and in Jeremy's memory we will be enjoying it more."

Mr Mitchell said he thought the last gliding fatality in Queensland was in 2006.

"It's not something that happens very often we are regarded as a very, very safe aviation sport."

He said three experienced senior instructors will investigate the accident with the police and advise the ATSB.

The club's social media pages said the location was a popular location for soaring all-year round.
