An unruly passenger has forced a Qantas A380 superjumbo to turn back shortly after taking off from London.
Flight QF2 bound for Sydney via Dubai returned to London's Heathrow Airport about an hour after take-off following "threatening behaviour" from a passenger, a spokeswoman for the airline said.
"The passenger was restrained by crew and the aircraft landed safely in London at around 11.50pm local time (10.50am AEDT). The aircraft was met by local authorities on arrival," she said.
The flight has since departed for Dubai.
A passenger on board the flight tweeted that the disruptive passenger looked to be "30-35 years old. Short, slightly rotund, went straight into the ambulance".
The Qantas A380, the world's largest passenger jet, is configured to carry 484 passengers: 14 in first class; 64 in business; 35 in premium economy and 371 in economy. Qantas has 12 A380s in its fleet, with eight more on order.
"This type of disruption inconveniences our customers and comes at significant cost to Qantas, but we take a zero tolerance approach to aggressive behaviour on board," the airline's spokeswoman said.
