More Theories But Still No Sign Of Missing Malaysian Jet

The search continues for Malaysia Airlines Flight 370 and the 239 people on board. They disappeared on March 8 when the jet apparently turned west while over the Gulf of Thailand. It was on a flight that should have taken it from Kuala Lumpur north to Beijing.

On Wired's website, pilot Chris Goodfellow explains why he thinks there's a good chance that a fire knocked out some of the plane's communications systems — and that the pilots were trying to get to a runway on the Malaysian island of Palau Langkawi. He concludes that:
