This August 1951 flight log page documents Lt. W. E. Bancroft's missions flying the PBM-5 Mariner flying boat on patrol across the Western Pacific, including repeated 'Patrol Formosa Straits' sorties. These flights were part of the U.S. Navy's neutralization patrol of the Taiwan Strait, ordered during the Korean War to prevent escalation between Communist China and Nationalist Taiwan, illustrating the wider Cold War stakes of the Korean conflict beyond the Korean peninsula itself.
