Qantas grounded its Airbus 380 superjumbo fleet after one blew out an engine Thursday, shooting flames and raining large metal chunks before making a safe emergency landing in Singapore with 459 people aboard.
It was most serious midair incident involving the double-decker A380, the world's largest and latest airliner, since it debuted in October 2007 with Singapore Airlines flying it to Sydney - the same route that Qantas flight QF34 was flying when it was stricken.
Qantas said there had been no explosion, but witnesses aboard the plane and on the ground reported blasts.
After the plane touched down in Singapore, the engine closest to the fuselage on the left wing had visible burn marks and was missing a section of plate that would have been painted with the red kangaroo logo of the airline. The upper part of the left wing also appeared damaged.
One passenger, Rosemary Hegardy, 60, of Sydney, told The Associated Press that she heard two bangs and saw yellow flames from her window.
