The plane circled back and landed at Sydney Airport shortly afterwards, where it was met by firefighters and police.

Upon landing, both equipment room doors were wide open and smoke was coming from one of the tires on the right side of the aircraft.

Although some reports suggest the plane took off with “fuel shooting out,” the airline has since clarified that the plane lost fluid through the right landing gear.
