Jetliner 'disappears' while flying from Malaysia to Beijing

The State Department confirms that three Americans were on a Malaysia Airlines jet that disappeared while flying from Malaysia to Beijing. The department says the U.S. Embassies in Kuala Lumpur, Malaysia and Beijing are in contact with families of the passengers. There's been no sign of wreckage but Vietnamese air force planes report spotting a pair of large oil slicks off the southern tip of Vietnam, where the jetliner with 239 aboard vanished.
