PLANES PLANNED FOR NEW COAST-HAWAII SERVICE

High olaced airplane engines are consplcucus no\v, as"is'wltnessed bv recent French and

British"sliips;~ "A "most interesting development is brought forth in a new desiga whieh is to ad-v-ance American transoceanic air travel. The Pan American Airways, a few days ago, let eontracts to fche Sikorsky AviaUon <»rporation and the Olenn L. Martin company, for construction work. The requLrements to be met, it is «xplained, were to 4©velop a standard transport for the longest overseas routes on world airways—that is, a maximum of 2,400 miles, San Francisco to Hawaii; and to carry about 50 passengers. One type

is an all-metal monoplane flying boat with four engines Btream-lined into the wing's leading edge. To attain such an operating radius, it was necessary to increase strength and rigidity with greater iighfcness; wliile eeonomie&l engines, usīsg fuel more efficiently for its weight, and propellers with eontrollable pitch—thus allowing maximmn efficiency aji any altitude, and the §uper-charging method, were inciuded in the specifications.

Ailoys for the structwre had to be proof agaiosfe the corrosion of peean. air. These preiiminary problems, it is axmounced, are consUiereci soive<i; an£, these great flying ships are toi be eonstru@ied in the expectation of an upturn iii internationai trarip
