Second Qantas jet engine fails

A Boeing 747-400 operated by Qantas, Australia's national carrier, with 431 passengers onboard has been forced to return to Singapore with an engine problem, Press TV reported.

The Boeing was carrying 412 passengers and 19 crew members and was headed to Sydney, CNN reported.

Passengers and eye-witnesses said that they saw flames coming from one of the four engines.

This comes one day after a Qantas Airbus A380 engine failed dramatically on a flight from Singapore to Sydney.

The Boeing passenger accounts were similar to what the people onboard the A380 experienced.

The A380 made an emergency landing after one of the four structures that house the engines was found to be missing.

The debris belonging to the Qantas plane landed among the people of the Batam Island in Indonesia. Eyewitness accounts say the people of Batam heard an explosion as the plane flew overhead.

Qantas and Singapore Airlines have grounded the superjumbo planes following the incident.

"We have decided that we will suspend all A380 takeoffs until we are fully comfortable that sufficient information has been obtained about the QF32... until we are completely confident that Qantas safety requirements have been met," said Qantas Chief Executive Alan Joyce.

The serial incidents can inflict serious damage to European aircraft maker Airbus and US aircraft maker Boeing's safety record and reputation.
