Two men have been injured and a plane completely destroyed after a fire erupted at an airport hangar in Perth's south.
Several fire, police and ambulance crews were called to Jandakot Airport just after 1pm today, where they found at least two sheds well alight.
Large plumes of thick black smoke could be seen billowing into the afternoon sky as almost two dozen fire officers battled the blaze.
Witnesses say a pilot aged in his 70s and his son were working on a plane in the hangar when there was an explosion, suspected to have started in a compressor, which ignited the blaze.
The duo rushed to try and protect three planes inside, but one was completely destroyed.
The younger man, aged in his 40s, suffered burns to his face, hands and legs and his father suffered burns to his hands.
They were treated at the scene before the younger man was taken to Fiona Stanley Hospital in a stable condition.
The damage from the fire is estimated to be more than $1 million.
