A Lion Air flight with 189 people on board has crashed into the sea just minutes after taking off from Indonesia's capital in a blow to the country's aviation safety record after the lifting of bans on its airlines by the European Union and US.
Indonesia's disaster agency posted photos online of a crushed smartphone, books, bags and parts of the aircraft fuselage that had been collected by search and rescue vessels that have converged on the area.
Spokesman Sutopo Purwo Nugroho said the aircraft, on a 1-hour-and-10-minute flight on Monday to Pangkal Pinang on an island chain off Sumatra, was carrying 181 passengers, including one child and two babies, and eight crew members.
Indonesian TV broadcast pictures of a fuel slick and debris field.
The National Search and Rescue Agency said the flight ended in waters off West Java that are 30 to 35 metres deep.

The agency's chief Muhammad Syaugi told a news conference that divers are trying to locate the wreckage of the plane, which according to aviation website Flightradar24 was brand-new and delivered to Lion Air in August.
Indonesia's Transport Ministry said the Boeing 737-800 plane, which took off from Jakarta about 6.20am (10.20am AEDT), crashed just 13 minutes later.
Data from aircraft tracking website FlightAware showed it had reached an altitude of only 1580 metres.
Indonesian TV showed dozens of people waiting anxiously outside the Pangkal Pinang airport. The transport ministry said crisis centres were set up Pangkal Pinang's airport and Jakarta's Soekarno Hatta airport.
The crash is the worst airline disaster in Indonesia since an AirAsia flight from Surabaya to Singapore plunged into the sea in December 2014, killing all 162 on board.
A report to the Jakarta Search and Rescue Office cited the crew of a tug boat which had reported seeing a Lion Air flight falling from the sky.
A telegram from the National Search and Rescue Agency to the air force has requested assistance with the search.

Lion Air is one of Indonesia's youngest and biggest airlines, flying to dozens of domestic and international destinations.
In 2013, one of its Boeing 737-800 jets missed the runway while landing on the resort island of Bali, crashing into the sea without causing any fatalities among the 108 people on board.
Indonesian airlines were barred in 2007 were flying to Europe because of safety concerns, though several were allowed to resume services in the following decade.
The ban was completely lifted in June this year. The US lifted a decade-long ban in 2016.
