## Description

Boeing flight-tests here, Sila builds silicon anode material next door, and the Port of Moses Lake sells the rest: Grant County International (MWH/KMWH) runs a 13,500-foot runway, the 17th longest in the United States. Inherited from Larson Air Force Base, closed in 1966, the field has the room to load and unload oversize freight and to handle cargo aircraft of any size, which makes it a standing option for technical stops and diversions across the dry Columbia Basin. Scheduled freighter services do not operate, but customs does: CBP works MWH as a user fee airport on weekdays from 08:00 to 17:00, and international departures need clearance arranged in advance. Regional produce – potatoes, apples and frozen foods – leaves by truck on Interstate 90 instead, about 290 kilometres west to Seattle-Tacoma (SEA) or some 170 kilometres north-east to Spokane (GEG), where the integrators and belly capacity sit. Flight test, maintenance and pilot training remain the core business; Japan Airlines trained crews over the basin for decades and AeroTEC continues the testing tradition. For shippers, MWH is the address for the awkward consignment – heavy, outsized or chartered – while routine air freight goes through SEA or GEG.
