Items resembling an emergency slide and plane door have been seen in the search for AirAsia flight QZ8501, which lost contact with air controllers on Sunday morning en route to Singapore's Changi Airport, Indonesia has said.

“We spotted about 10 big objects and many more small white-coloured objects which we could not photograph,” an Indonesian air force official, Air Vice-Marshall Agus Dwi Putranto, told a press conference.

“The position is 10km from the location the plane was last captured by radar,” he said.

He displayed 10 photos of objects resembling a plane door, emergency slide, and a square box-like object. Indonesian TV also showed a live stream of the floating debris.

“It is not really clear... it could be the wall of the plane or the door of the plane,” he said.

“Let’s pray that those objects are what we are really trying to find,” he said in Pangkalan Bun in Central Kalimantan on the island of Borneo.

     

An AFP photographer on the same flight that spotted the debris said he had seen objects in the sea resembling a life raft, life jackets and long orange tubes.

Indonesian TV showed two relatively large objects, one orange and one grey or brown, floating on the surface. The largest appeared to be several metres in length.

“Hopefully we will find something definite because I haven’t received anything else,” an Air Force official told MetroTV, referring to the reported debris. “Other aircraft are still carrying out searches.”

A search aircraft has spotted debris 105 miles (169km) off Pangkalanbun, and they now sending a chopper for a clearer look, according to reports.

"These look like items that are not usually seen on sea surface," MetroTV cited Mr Dwi Putranto as saying. The aircraft was flying 500 feet (152.4m) above sea level. A chopper would allow the team to get a better look.

The debris is in a sea area of 10 sq km to 20 sq km, east of where the plane was last detected on Sunday, MetroTV cited Mr Dwi Putranto.

Sea current direction trend in the area has been easterly, MetroTV reported.AirAsia flight QZ8501 disappeared on Sunday morning over the Java Sea with 162 people on board.

The search is focused on waters around the islands of Bangka and Belitung in the Java Sea, across from Kalimantan.
