62 people were on board.

The Sriwijaya Air flight 182 -- a Boeing 737-500 -- was heading from Jakarta to the city of Pontianak, on the Indonesian side of Borneo.  It lost contact at 2:40 p.m. local time, 11 nautical miles north of Jakarta's Soekarno-Hatta International Airport.   After 4 minutes into the flight, and amid heavy rains, the plane dropped 10,000 feet in less than a minute before disappearing from the radar, according to the global flight tracking service Flightradar24.
