Adak Island
One of the major successes of Castner's Cutthroats was the building of an airfield on Adak Island. The U.S. Army Air Forces had lost several planes, not to the Japanese, but to Alaskan weather. In order to shorten the distance between the Japanese and American air bases, an airfield on Adak Island was proposed and Castner's Cutthroats were sent in to scout for a suitable location. Due to the mountainous terrain of the area, no acceptable site was available. Instead, Castner's Cutthroats dammed a lagoon and drained it to use the sandy bottom floor as a temporary landing strip. Engineers later came in and improved the area.
