The search for a missing Malaysian jetliner with 239 people onboard could expand westward into the Indian Ocean based on information that the plane may have flown for four hours after it dropped from radar, U.S. officials said Thursday.

A senior American official said the information came from a data stream sent by Malaysia Airlines Flight 370. If the two engines on the Boeing 777 functioned for up to four additional hours, that could strengthen concern that a rogue pilot or hijacker took control of the plane early Saturday over the Gulf of Thailand.

All other communication with the plane ended after 1 a.m. At that point, the pilot signed off with Malaysian air traffic controllers with a casual “All right, good night,” according to news reports. Within 30 minutes the transponder signal the plane was sending to ground-based radar stations went dark.

If the plane flew on for hours, it’s likely that someone in the cockpit manually turned off the transponder and the radio.

“The fact that a modern airplane with a huge amount of redundancy appeared to change course at the same time that the transponder was turned off, that suggests that someone unauthorized took control of that airplane, like an intruder or one of the pilots,” said a U.S. flight crash expert who spoke on condition of anonymity because is not directly involved in the investigation.

Other U.S. officials said their information did not reveal in what direction the plane flew — or whether it simply circled — during that time. Four hours of additional flight could have put the plane somewhere over the Indian Ocean, far from its Beijing destination, prompting officials to consider whether the search area should be expanded.

Modern airplanes send some information in a steady stream to their owners, the company that built them or the firm that built their engines. In the final minutes before Air France Flight 477 plunged into the Atlantic almost five years ago it sent 29 automatic error messages to the airline’s home base in France.

The Wall Street Journal first reported that U.S. investigators suspect that the engines on the Malaysia Airlines flight kept running for up to four more hours after the plane reached its last known location. The paper later corrected its report to say that this belief was based on satellite data that was designed to report on the status of some onboard systems, not signals from monitoring systems embedded in the plane’s Rolls-Royce engines. The Malaysian government denied the initial report.

In Washington, one senior administration official said the data about the plane engines came from the Aircraft Communications Addressing and Reporting System, or ACARS, a way that planes maintain contact with ground stations through radio or satellite signals. The official, who spoke on condition of anonymity because of the sensitive nature of an ongoing investigation, said Malaysian authorities shared the flight data with the administration.

Malaysian authorities had earlier said that engine data was unavailable after the plane disappeared from civilian radar at 1:30 a.m. on Saturday. The last transmission from the engines came 26 minutes after takeoff from Kuala Lumpur, Malaysia Airlines chief executive Ahmad Jauhari Yahya said.

“The last transmission was received at 1:07,” Ahmad told reporters. “It said everything is operating normally.”

Representatives from both Boeing and Rolls-Royce have been in Kuala Lumpur working with the airline, and neither received data after 1:07 a.m., Ahmad said. A Rolls-Royce spokeswoman refused to comment on the reports.

The search for Flight 370 has at times appeared chaotic and baffling — a mix of rumors, confusion and red herrings. The government in Kuala Lumpur acknowledged Thursday that it has made little progress in solving the mystery of the vanished plane.

“We have looked at every lead. In many cases, in fact all the cases, we have not found anything positive.” said Hishammuddin Hussein, Malaysia’s defense minister and acting transport minister.

“This just might be something we have never seen before,” said Steven Wallace, former director of the Federal Aviation Administration’s office of accident investigation, in an interview on Thursday.

Wallace said progress may be hampered because Malaysia lacks an investigative branch like the U.S. National Transportation Safety Board.

“The pattern here is that the best information is not being immediately presented to the smartest people around who could look at it,” Wallace said. He noted that Malaysian authorities only revealed after several days that their military radar had picked up signs of a mysterious plane flying off Malaysia’s western coast after the passenger jet disappeared much further east.

Then, China disclosed three days after the fact that its satellites had picked up images of what appeared to be debris in the area where the plane might have vanished. No signs of the wreckage were ultimately found there.

“And then we have this new business about the engines sending [signals] automatically, also several days old,” said Wallace.

And the information about those engine signals is fraught with contradictions.

“Between Rolls Royce and Malaysia Air, they know whether they have that technology in place, yet we get conflicting reports,” he said.

In Washington, White House press secretary Jay Carney told reporters that the United States is not in a position to draw any conclusions. However, he added, “it’s my understanding that based on some new information that’s not necessarily conclusive — but new information — an additional search area may be opened in the Indian Ocean.”

Search operations in the Indian Ocean, the world’s third-largest ocean with an average depth of nearly 12,800 feet, would present significant challenges.

The United States is “consulting with international partners about the appropriate assets to deploy,” Carney told reporters Thursday.

As the search area continued to widen, with nearly a dozen countries involved, the U.S. Navy said Thursday that it was shifting one of its ships involved in the hunt, the destroyer USS Kidd, from the Gulf of Thailand to the Malacca Strait on the western side of the Malay Peninsula.

The U.S. military also announced that it would add a P-8A Poseidon aircraft to the search on Friday. It will join a Navy P-3C Orion surveillance aircraft already patrolling in the area.

India’s Defense Ministry said Thursday that the Indian navy has launched its own search mission, sending two ships — the INS Kumbhir, an amphibious warfare ship, and the INS Saryu, a patrol vessel — into the Andaman Sea near the Malacca Strait. Indian coast guard and navy aircraft were also pressed into service.

Burma said it would open its airspace to planes looking for the missing airliner and was prepared to join the search if asked, the BBC reported.
