FSX – Ofu Island Airport, American Samoa NSAS. Welcome to Ofu Airport, located on the island of Ofu, in the beautiful Pacific Paradise of American Samoa. The small airport features a sealed runway, but has no night lighting, no beacons or navigation aids, and also no apron, with aircraft parking on the runway or the grass beside the very small terminal. Vaoto Lodge is right beside the end of the runway, and is the best place for tourists to stay on the island. By Lawrie Roache.
