A Qantas flight bound for the US has had to divert due to a medical emergency, forcing the flight to return to Sydney Airport after four hours in the air. Australian Olympic diver Sam Fricker shared footage from the flight, which also saw the aircraft dumping fuel over the ocean. The flight landed safely and was met with emergency services on arrival at Sydney Airport. The incident occurred during Australia's ongoing fuel-crisis, which has led to high petrol and diesel prices.
