Powelson Air Service    Stinson SM-6000-B     NC12130               (c/n  5055)

                              

                                  Following the succesful operation of the Stinson Reliant on the San Juan to Ponce route in 1938,
                                  Powelson Air Services acquired four tri-motor Stinson Ts, two of which are seen above in this
                                  old print from the William W. Sierra collection.      (Officially designated the SM-6000-B, this
                                  Stinson was often referred to as the Model T).    With the introduction of the larger aircraft, the
                                  route was expanded to the Virgin Islands.    Caribbean-Atlantic Airlines, Inc.was incorporated
                                  on 27 February 1939 and in June of that year took over the operation of Powelson Air Services.
