An Indonesian helicopter searching for the missing AirAsia jetliner saw two oily spots in the water Monday, and an Australian search plane spotted objects elsewhere in the Java Sea, but it was too early to know whether either was connected to the aircraft and its 162 passengers and crew. An Australian Orion aircraft had detected 'suspicious' objects near Nangka island about 100 miles off central Kalimantan. That's about 700 miles from the location where the plane lost contact. Air Force spokesman Rear Marshal Hadi Tjahnanto told MetroTV that an Indonesian helicopter saw two oily spots in the Java Sea east of Belitung island. He said oil samples would be collected and analyzed to see if they are connected to the missing plane. The twin-engine, single-aisle plane, which never sent a distress signal, was last seen on radar four minutes after the last communication from the cockpit.
