The U.S. is helping in the search for that missing jetliner off the coast of Malaysia.
The Pentagon, the FAA, even the FBI are all involved in helping Malaysian officials figure out what happened.
The Pentagon dispatched two Navy destroyers with search helicopters. Plus surveillance aircraft from Okinawa, Japan to help with the search off the coast of Malaysia where the weather is getting worse. "Our radars are very advanced and they can actually negate a lot of that surface clutter," said Commander William Marks, U.S. Navy.
The plane had seven hours of fuel, so the search area is expanding. "You really have to start looking at a trajectory path at a speed an altitude that they were at, how far could this airplane go," said NTSB Investigator Greg Feith.
Two investigators from the FAA, and two more from the National Transportation Safety Board are in Malaysia trying to help pinpoint just how far this plane could've gone. "The only way in certain parts of the world where they are going to be able to locate your position is by knowing where your last position was and what your next position was predicted to be," said Former American Airlines Pilot Tom Casey.
The State Department says three Americans were on board. Their family, friends and neighbors anxiously await news. "It's really sad because it's like you're waiting for them to come home," said Michele Heck, Mei Ling Chng's Neighbor
Greg Candalaria was supposed to be on flight 370, but he cancelled at the last minute. "By the grace of God I was not on that plane," said Candalaria,
239 people were. The search now enters its fourth day.
