Qantas plane has engine problems

What the hell is happening at Qantas Airlines?

Once one of the most reliable carriers in the world, Australia's national airline has been beset by mechanical problems over the past few years and that has cast doubt over the reliability of the company's fleet.

Qantas' latest incident: One of its Boeing 747s was forced to make an emergency landing in Bangkok after the pilot shut down one of the plane's Rolls-Royce-powered engines while on a flight to London.  According to Qantas, the pilot noticed “vibration and high temperatures” in one of four engines and managed the land the plane with 308 passengers aboard without incident.

However, this latest incident may have more to do with Rolls-Royce than Qantas. That's because earlier this week a Cathay Pacific plane made an emergency landing in Singapore after the pilot noticed sparks coming from his plane's Rolls-Royce engines.
