Flightradar24 said the flight was operated by a Boeing 737-500 “classic” with registration number PK-CLC (MSN 27323).

The plane took off at 07:36 UTC time and the ADS-B signal was lost minutes later, at at 07:40:27. It was en route from Jakarta to Pontianak in Indonesia.

The Ministry of Transportation office in Jakarta confirmed to ABC News that the flight lost contact after departing from Soekarno–Hatta International Airport in Jakarta.

“The missing plane is currently under investigation and under coordination with the National Search and Rescue Agency and the National Transportation Safety Committee,” they said in a statement.

ABC News confirmed 62 people were on board: 56 passengers and six crew members.

“We are aware of media reports from Jakarta, and are closely monitoring the situation,” Boeing said in a statement. “We are working to gather more information.”

The highest altitude it reached was 10,900 feet and the last altitude recorded was 250 feet.

A search for the plane is now starting and the situation is under investigation.
