Indonesia asks for US help finding missing plane; US says it's looking for best ways to help

The State Department said Monday that Indonesia has asked the United States for help in locating a missing AirAsia jet, and the Pentagon said it could include detection equipment deployed by air, surface and sub-surface.

The jet carrying 162 people is believed to have crashed into Indonesia's Java Sea. The State Department says no Americans were on board.

The U.S. Embassy in Jakarta received a diplomatic note from Indonesian officials on Monday asking for assistance finding the plane. State Department spokesman Jeff Rathke says the U.S. is identifying how best to help, but that it will take some time to review the request.

The Pentagon's press secretary, Rear Adm. John Kirby, said in a brief statement that while details are being coordinated, the assistance "could include air, surface and sub-surface detection capabilities."

"We stand ready to assist in any way possible," Kirby said.

AirAsia Flight 8501 vanished Sunday morning on its way from Surabaya, Indonesia, to Singapore.
