A non-stop flight by Naval seaplanes to the Hawaiian Islands will be undertaken this summer. The planes will take off from either San Diego or San Francisco. Two planes which have been developed at the Naval Aircraft Factory in Philadelphia will participate in the flight while a third which is now building at the plant of the Boeing Airplane Company in Seattle will be used if completed in time for the initial attempt.
