Planes are believed to have collided on a property and crashed to the ground, killing an 80-year-old Caboolture man and a 77-year-old Glenwood man.

The police are investigating the cause of the crash.

“The evidence suggests that each aircraft likely had a single male occupant and both men died,” said Inspector Brad Inskip.

“We’re going to look at the possibility that there was a mid-air collision, but it’s very early days and we’re really not sure.”

Inskip believes the aircraft is a single-occupant glider and microlight.

Police, ambulance and fire brigade were on duty.

A man who lives on a neighboring property witnessed the incident.

“We were sitting on the porch having a cup of coffee and we heard a big bang,” he told 7NEWS.

“We didn’t think it sounded like a shot and when we looked up we saw white chunks of airplane falling from the sky.

“It was already broken… I didn’t see much of the second plane.”

He said he called triple zero immediately and the police were there quickly.

The police are preparing a report for the coroner, while the traffic authorities are also investigating.
