A Sriwijaya Airplane, a Boeing 737-500, lost contact soon after takeoff from the Indonesian capital of Jakarta on Saturday, January 9.
Flight tracking showed the flight path ending off the coast just north of Jakarta after losing altitude, The Hindu reported.
The plane lost over 10,000 feet of altitude in less than a minute, reported flight tracker website FlightRadar24.
It said that Flight #SJ182 'was operated by a Boeing 737-500 "classic" with registration number PK-CLC (MSN 27323). First flight for this aircraft was in May 1994 (26 years old).'
The plane, carrying over 50 passengers, took off from Soekarno-Hatta Airport and was heading to Pontianak.
