Qantas flight turns back after engine problems

A Qantas flight from Bangkok to London has been forced to return to Bangkok after one of its engines began experiencing trouble shortly after takeoff.

The Australian carrier says there was an increase in vibration and high temperatures in one of the plane's four engines on Friday. The pilots shut the engine down and landed the Boeing 747-400 soon after.

Qantas says it believes the cause of the engine trouble is similar to issues other airlines are having with Rolls Royce engines. A Cathay Pacific plane made an emergency landing in Singapore on Monday after its Rolls Royce-made engine caught fire.

Rolls Royce came under increased scrutiny in November after one of its Trent 900 engines on a Qantas A380 disintegrated after takeoff from Singapore.
