The rare photo above is from the William W. Sierra collection.
Billy indicates that
he thinks
the individual on the extreme right is Powelson. Billy's father, Jose
M.Sierra was to be-
come Chief Pilot and
Operations Manager for Caribbean-Atalantic Airlines which took over the
operation of Powelson Air
Service in June 1939. By the way, the Aeronca
