What Really Happened To Malaysia Airlines Flight MH370?!?

I'm no conspiracy theorist, as those of you who follow this site already know. I try to deal with known entities, my Tin Foil Hat is somewhere in the garage. But the more I hear about this flight that just disappeared somewhere over the water, the more I wonder what's really up.

The mystery involving Malaysia Airlines Flight MH370 deepened more than three days after it dropped off the radar, as officials widened the massive search even further and signaled that fears of terrorism were probably off the mark

As the sun set here on the fourth day since Malaysia Airlines Flight MH370 vanished, the case of the ill-fated jetliner was as muddied as Kuala Lumpur’s skies, steeped in a dense haze that seasonally blankets the Malaysian capital.

We’ve made no progress, we don’t have a clue,” Izhar Bahari, air traffic controller at Malaysia’s Department of Civil Aviation, tells TIME. He went on to deny an earlier report that the search has now shifted focus to the Strait of Malacca. “We focus our search both on the east and the west coast, and we will expand the areas for tomorrow.”

Authorities said Tuesday that despite suspicions raised by the fact that two of the passengers held stolen passports, one was a 19-year-old Iranian asylum seeker with no terrorist ties. The revelation seemed to deflate fears that the disappearance was an act of terrorism.

“The more information we get, the more we are inclined to conclude it is not a terrorist incident,” Interpol Secretary General Ronald Noble said, according to Reuters.

Scouring a radius of over 100 nautical miles, dozens of aircrafts and ships from 10 countries explored both the area where communications were lost with the Boeing 777, between Malaysia and Vietnam, and a swath to the southwest. Based on radar information suggesting that the Beijing-bound aircraft may have attempted to turn back to Kuala Lumpur, the search was increasingly focused off the coast of Malaysia.

Officials have pleaded to media and the public to refrain from spreading unverified information. But with 239 lives presumed lost, rumors abound. In lieu of hard evidence, journalists had latched on to the fact that two passengers traveled on stolen passports, but that lead seemed to lose weight on Tuesday, as one of the two men’s identities was revealed.

I'm not a betting man, but if I was, I'd put money on "electrical malfunction". But that's just me being lazy and rational.

I'm sure ya'll have some theories on this. Weigh in below?
