Lion Air's flight JT-610 was heading to Pangkal Pinang, an island north of Indonesia's capital when it lost contact with air control about 6.33am local time (10.33am AEDT, 11.33pm BST) - just 13 minutes after take-off.
Before the tragic accident, the plane's pilots had asked for a return to base before the aircraft vanished from the radar, The Strait Times reported.
A tug boat leaving the capital's port saw the plane falling into the water, which is reported to be about 30-35m deep.
