PLANS FOR SERVICE ACROSS PACIFIC REVEALED
NEWEST CLIPPER TRANS-OCEANIC TRAINING SHIP
Fuel Tanks For 3,000-Mile Range Installed in Brazilian Clipper’s Sister Ship
NEW INSTRUMENTS
Will Enable Marine Crews to Apply Navigation Expertness on Long Range Tests
BRIDGEPORT. — The second giant Sikorsky 4-engined flying boat, nearing completion here for the Pan American Airways System, is being fitted out as a “training ship” for trans-ocean experimental flight operation. This new ship, designated simply as “Clipper Number 5”, in addition to many advanced instrument installations, has been equipped with huge tanks to carry more than SV2 tons of fuel. This fuel load will give the giant flying boat a cruising range of better than 3,000 miles, 1,000 miles greater than the Bermuda-Azores stretch across the Atlantic and 600 miles more than the distance between California and Hawaii.
In addition to the regular transport flight equipment carried on all the Pan American Clipper Ships, “Clipper Number 5” has had installed new type instruments and mechanical aids, several of which were designated specifically for use on the experimental service Pan American plans to operate across the Pacific in the near future.
New Instruments Designed
A special pumping system has been devised to convey the fuel from the 1,320-gallon cabin tanks into the wing tanks which have a capacity for an additional 1,270 gallons. Tanks have also been installed to carry better than a half ton of oil. A new device has been perfected by engine manufacturers to provide for forced lubrication of rocker arms and other lubrication during flight. An electrical device by which the 4 engines can be synchronized perfectly, an instrument recently developed by Pan American engineers, and a new meter with which to measure the rate of flow of gasoline into the carburetors, are among the special instruments added Continued on Page 2
After two years of closely guarded construction a new and greater Flying Clipper Ship, Pan American's giant "Clipper Number 7", emerges from blue-prints into dural at the Glenn L. Martin Company plant, near Baltimore.

World’s Fastest Airliners Being Introduced in West Coast, Central American Service
LIMA.—Pushing ahead with its progressive policy of providing the countries of the South American west coast, Uruguay and Argentina with the highest possible type of international air transport service, Pan American-Grace Airways has placed in service three new Douglas airliners, the most advanced type of land transport planes in the world at the present time. A fourth ship of the same design will be added to the fleet early next year, probably in February.
Appreciating the benefits of improved transportation and communications to their respective republics and to South America as a whole, government officials, business men and the general public of the west coast, turned out in large numbers to see and welcome the first Douglas transport as it flew its first fleet trip down the Pacific seaboard.
“Congratulations were received from all sources and the west coast press universally carried enthusiastic reports regarding the new ship,” J. D. MacGregor, vice-president and general manager of Continued on Page 4

BROWNSVILLE. — The three new Douglas transports, world’s fastest passenger planes, delivered to the Western Division in September, are now in preliminary operation on the former regular schedules between Brownsville and Mexico City, Erwin Balluder, division manager, reports. The fleet new ships cut a sizeable chunk out of the former flying time on this run, but no schedule changes are to be made until the new general schedules planned for March 1 are put into effect throughout the Pan American System permitting the Western Division to coordinate its connections with the new Douglas service of Pan American-Grace Airways south of Cristobal.
The arrival of the new Douglas ships in the Western Division attracted widespread attention from the public and columns of favorable publicity from the press. “They were a sensation in the valley towns of the Rio Grande and at every port in our division where they have been seen,” Mr. Balluder reports.

Administration Encouragement Placed Behind Pioneer Move to Link U. S. and Orient
WASHINGTON. — Encouragement of the Roosevelt administration was extended to the Pan American Airways System for its proposed experimental air service to link California and the Orient, the plans for which have been advanced to the point where the actual inauguration of the first trans-ocean service is scheduled for the near future.
The plans for such a service, toward which Pan American has concentrated technical studies and aircraft development during the past several years, were made public by the Post Office Department through an exchange of letters between Postmaster General James A. Farley and J. T. Trippe, president of the Pan American Airways System.
Service Long Planned
Advising of the practicability of establishing the first trans-oceanic air transport service, Mr. Trippe’s letter to the Postmaster General stated:
“As you are aware, the Pan American Airways System several years ago began the necessary preliminary development work in connection with the future establishment of trans-oceanic air services, as have the international airlines of several European nations.
“In 1932, we commenced the construction of four-engine flying boats suitable for trans-Pacific service. In the Far East, we have developed, jointly with the Chinese Government, an extensive air transport system, with some 3,000 miles of airways now in operation. We have already completed extensive ground and meteorological surveys covering the route frgxnr'the United States to the principal trade centers of the Far East. Our technical staff, headed by Colonel Lindbergh, is now studying the question Continued on Page 2
