Officials tell CNN the search for the missing Malaysia Airlines flight 370 is now extending west into the Indian Ocean.
The shift comes after new information suggests the mystery flight remained in the air several hours after disappearing from radar.
If the plane did go down in the Indian Ocean, recovering the wreckage could be a difficult task.
It took nearly two weeks to discover the block boxes after TWA Flight 800 crashed off the coast of Long Island in 1996.
It was four years before the investigation was complete.
Suzanne Malveaux reports it took even longer to recover parts of the plane.
The search is expanding for missing Malaysia Airlines flight 370.
U.S. officials now believe the plane may have flown four to five hours after its last communication with the ground.
But what if the vanished plane is never found?
That's been the case with dozens of planes over the years.

(CNN) - A US Airways plane blew a tire during takeoff Thursday evening at Philadelphia's airport, an airline spokesman said, with witnesses adding that they saw the plane "bounce" before screeching to a halt.
Citing initial reports, US Airways spokesman Todd Lehmacher said the commercial airliner's pilot decided to abort takeoff following the tire issue. Federal Aviation Administration spokesman Jim Peters noted the plane's front wheels collapsed, as photos indicate.
One person aboard ended up requesting medical assistance, said Lehmacher. Similarly, a Philadelphia fire department spokesman told CNN that there was one minor injury.
Passengers on the Florida-bound flight subsequently got off the plane and onto the runway, where they were picked up.
"Our crew safely evacuated the passengers," Lehmacher said. "We are accommodating passengers on a new aircraft, which is scheduled to depart later this evening."
Flight 1702 was scheduled to take off at 5:50 p.m. and arrive in Fort Lauderdale about three hours later, according to US Airways' website, though the FAA's Peters said the incident took place around 6:25 p.m.
(CNN)- Two U.S. officials tell ABC News that the two communications systems on Malaysia Airlines Flight 370 were shut down separately.
A source tells ABC that indicates the plane was not taken down by a catastrophic failure, meaning it could very well have been a deliberate act.
The two communications systems are the data reporting system, which they believe was shut down at 1:07am, and the transponder, which transmits location and altitude, was shut down at 1:21 am.
"This had to have been some sort of a deliberate act," aviation analyst for ABC's World News John Nance told CNN's Erin Burnett, adding that it's "likely a human-being was pulling circuit breakers at a sequential time."
This latest information comes on the heels of a senior U.S. officials telling CNN that the missing Malaysia Airlines plane may have flown for four to five hours after its last contact.
Officials now believe the plane may have made it to the Indian Ocean - the complete opposite direction of where the search was headed Wednesday.
Malaysian authorities believe they have several "pings" of plane data that were transmitted to satellites in the four to five hours after the last transponder signal.
Authorities believe during that time the plane could have flown towards the Indian Ocean.
But like everything else in this mystery, no one is really sure.
The search area and flight path of Flight 370 is not clear. But what is certain -is the Air traffic controllers lost contact with the plane around 1:30 a.m.
Malaysian officials at first said the plane u-turned, flying for about another hour.
Chinese officials on Wednesday released satellite pictures showing what might have been plane debris. But no evidence of debris was found and that theory was dismissed.
