Hao Airport — Otepa, French Polynesia

HOI is Hao Airport, located on Hao Atoll in French Polynesia, a remote coral atoll in the Tuamotu Archipelago. The airport gained historical significance as a logistics and support base for France's nuclear testing program in the Pacific during the 20th century, giving it a longer runway than many other atoll airstrips in the region. Today HOI serves as a transit point connecting the sparsely populated Tuamotus to Tahiti, supporting both local residents and limited tourism to this remote part of the South Pacific. Its isolated setting reflects the vast distances between French Polynesia's scattered island communities.
