KLM (Royal Dutch Airlines) Flight 844 was an international scheduled passenger flight from Biak-Mokmer Airport, Dutch New Guinea (now Indonesia) to Manila International Airport, Manila, Philippines on 16 July 1957, which crashed into Cenderawasih Bay 1.2 kilometres (0.75 mi; 0.65 nmi) from its departure airport.

With a construction number of 4504, the aircraft first flew in 1953 and accumulated 11,867 hours of flight.

[2] Initially the crash was attributed to pilot error and/or technical failure, with no direct evidence for either cause.

As the accident happened at night, the pilot might have misjudged his altitude relative to the sea.

[1] The summary of the report from the Accident Board noted that there was no evidence of either pilot error or technical failure, but also noted that the risks involved in take-off and landing should not be needlessly increased by carrying out low passes on scheduled services with passengers aboard.
