Garuda Indonesia Flight 542 was a scheduled passenger flight on 3 February 1961, which was reported missing en route from Surabaya to Balikpapan. All 26 occupants on board were lost in the accident.^[1]

The aircraft departed Surabaya-Juanda Airport at 11:35 pm inbound for Balikpapan. While in cruising altitude, the airplane disappeared from radar screens and presumably crashed into the Java Sea. Search and rescue operations were conducted but eventually suspended after a few days, as no trace of the aircraft nor the 26 occupants was found. The crew was unable to send any distress call prior to the accident. Due to a lack of evidence, it was not possible to determine the exact cause of the accident.
