Queensland Police say the red biplane went missing near the town of Kilcoy on Monday afternoon, after it failed to return to the Caboolture airport around 2.15pm (AEST).

It is believed the pilot, Des Porter, and five passengers on board the plane may have been forced into an emergency landing

Porters’s father and brother were killed in the 1950s in a crash involving the same model airplane.

The plane had left an airshow at Monto and had been due to arrive at Caboolture Airport, north of Brisbane, about 2.15pm (AEST), but never arrived.

Mr Porter was 10-years-old when he survived a crash in the same model of aircraft, a de Havilland Dragon, in 1954.

His father – the pilot – and his older brother were killed when the airplane went down in a creek in Brisbane’s south.

A distress call from Mr Porter shortly after 1pm (AEST) on Monday was picked up by a Nine Network helicopter pilot.

Mr Porter said he was having difficulty positioning himself and wanted assistance, the Nine pilot said.

Police believe there is the pilot and five passengers on board the plane.

Police and AuSAR are coordinating an air and land search west of the Imbil area.

Caboolture Aero Club president John Dawson said the pilot on the missing airplane was a friend.

“I hope that he’s safe”.
