This Sentinel served with air force, army and coast guard, but not with the marines, although it now carries marines markings... It was delivered as 42-15060 to the USAAF in May 1943. From 1943 until 1948 it was operated by a range of units, both army ground units and air force units (including air transport command, strategic air command). In the 1950s, the aircraft was operated by the USCG as OY-1 with serial 5060. In 1959 it was sold to the private market as N 9315H.
