SINGAPORE - PASSENGERS aboard a Qantas A380 superjumbo that made an emergency landing in Singapore after a mid-air engine failure left the city-state for Sydney on Friday, the airline said.

Flight QF8032, chartered by the Australian flag-carrier to ferry the affected passengers, left Changi Airport at 11.10am (0310 GMT), a Qantas spokesman told AFP.

The passengers had stayed overnight in Singapore after the Sydney-bound double-decker Airbus made a dramatic turnaround after experiencing engine trouble shortly after taking off from Changi on Thursday.

Passengers recounted loud bangs and a fire on the superjumbo shortly after take-off, and said the atmosphere inside the cabin was tense but calm as the plane circled over Indonesia to dump fuel ahead of the forced landing.

The A380 plane carried 466 passengers and crew but the Qantas spokesman would not say how many were aboard the chartered flight on Friday.

A Qantas statement said the flight was expected in in Sydney at 8.45pm (0945 GMT, 5.45pm Singapore time). It added that Qantas was 'in discussions with other carriers regarding aircraft charter options' to ferry other passengers affected by the suspension of all Qantas A380 flights after Thursday's incident.
