An outsize in aircraft : The big Latecofere flying boat at the Biscarosse seaplane base during its trials. THE new Latecoere 37-ton flying-boat, the Lieutenant Paris, which is equipped with six Hispano-Suiza 860 h.p. liquid-cooled engines, began its trials at the Biscarosse seaplane base last week. With a six-ton load this machine made its initial flight around the lake on January 16, flying at a height of about 600 ft. These tests will be continued with gradually increasing loads until a loaded weight of 37 tons is reached. One of the largest boats yet constructed, the Lieutenant Paris has been designed as a passenger transport and postal machine which can be adapted for several different ser vices. For operation on the Air France Marseilles-Algiers line, the machine can be equipped to transport seventy- two passengers with a crew of four. Its total weight for this service will be 69,519 lb. divided as follows: — Weight empty, including equipment Fuel Crew (four men) Seventy-two passengers (approximately 31 tons) 43-454 lb. 9,394 lb. 880 lb. 15,791 lb.

In making the trip from France to the United States, it is designed to make the crossing with a stop at the Azores and transport twenty-four passengers. In both these crossings the machine, when fully loaded, will weigh thirty- seven tons. The following are the estimated performance figures in fully loaded condition: — Speed at ground level, 150 m.p.h. (250 km/h); speed at cruising height, 125 m.p.h. 201 km/h); ceiling, 16,400 ft. (5000 mi; range with no wind, 2,812 miles (4300 km). The Lieutenant Paris is constructed of duralumin and stainless steel throughout with the exception of the fabric covering of the outer wing panels and the tail. The hull consists of two sections: the main hull and the super structure which covers almost its entire deck. The main hull is constructed with a heavy keel and equipped with two steps. It is divided into seven water tight compartments, in which all the longerons, stiffeners ind cross struts are of open section and easily inspected, ihe forward part of the hull contains a hold for storing mooring tackle, anchors, and so on.
