UPDATE 10:42am: Victoria Police have now confirmed that the plane crashed shortly after takeoff. Mayday calls were made by the pilot of the plane, and police understand the cause of the crash is “catastrophic engine failure.” Reports now also confirm that all staff inside the DFO were safely evacuated.

EARLIER: Reports are emerging of a crash at Melbourne’s Essendon Airport, with early word suggesting that a light plane may have run off the runway.

Both the Calder and Tullamarine Freeways are now closed in both directions as authorities attend to the scene.

Motorists travelling along the freeway at the time reported thick plumes of black smoke rising from the runway of the airport; Melbourne’s smaller airport used for charter and special-service air vehicles.

Details at the moment are sketchy, but initial reports from the scene are indicating that the vessel may have crashed into part of the neighbouring Essendon Fields DFO shopping outlet.

At least eight fire crews are attending the scene, according to Fairfax Media.

Footage shot moments ago from the scene shows the horrific-looking scene, with extensive damage to the exterior of the DFO apparent.

No word yet of any potential injuries in the incident.

The aircraft, initially reported to be an air ambulance, was reportedly carrying up to 5 passengers.
