Nanga Pinoh Airport — Nanga Pinoh-Borneo Island, Indonesia

NPO is Nanga Pinoh Airport, a small regional airstrip serving Nanga Pinoh on the island of Borneo in Indonesia's West Kalimantan province. The town sits along the Melawi River in a heavily forested interior region, where river and air transport have traditionally been more practical than roads. NPO provides a lifeline for the local population, supporting light aircraft flights connecting Nanga Pinoh to Pontianak and other regional centers. The airport's traffic is modest, consistent with the area's remote, timber- and agriculture-based economy, and it remains one of the few reliable transportation links for communities scattered through this part of Borneo's interior.
