U.S. investigators told ABC News that the two modes of communication were "systematically shut down."
That means the U.S. team "is convinced that there was manual intervention," a source said, which means it was likely not an accident or catastrophic malfunction that took the plane out of the sky.
U.S. officials said earlier that they have an "indication" the missing Malaysia Airlines jetliner may have crashed in the Indian Ocean and is moving the USS Kidd to the area to begin searching.
It's not clear what the indication was, but senior administration officials told ABC News the missing Malaysian flight continued to "ping" a satellite on an hourly basis after it lost contact with radar. The Boeing 777 jetliners are equipped with what is called the Airplane Health Management system in which they ping a satellite every hour. The number of pings would indicate how long the plane stayed aloft.
It's not clear, however, whether the satellite pings also indicate the plane's location.
The new information has greatly expanded the potential search area into the Indian Ocean.
"We have an indication the plane went down in the Indian Ocean," the senior Pentagon official said.
