Flight 6715: Vanished Over the Molo Strait: Introduction

Thu, 02 Apr 2026 00:00:00 GMT

Fourteen people boarded a small turboprop on the morning of January 10, 1995, at Sultan Muhammad Salahudin Airport on the island of Sumbawa.

The aircraft -- a de Havilland Canada DHC-6 Twin Otter 300, registered as PK-NUK and named Sangihe -- never arrived. Somewhere over the Molo Strait, the narrow body of water between Sumbawa and Flores, the plane and everyone aboard simply vanished. No wreckage was recovered. No bodies were found. No emergency transmission was received. Merpati Nusantara Airlines Flight 6715 became one of the enduring mysteries of Indonesian aviation, a disappearance made all the more haunting by the modest scale of the flight and the completeness of the silence that followed.
