APRIL 9,194287 THE A ORE PLANE SPOTTER AIRCRAFT IN THE NEW S-LV THE HEINKEL He 177 THE HEINKEL He 177 is Germany's latest heavy bomber. Although its design was begun in 1939 and it first flew in the Summer of 1940, the enemy ran into a lot oi trouble with this aeroplane, and it was only just beginning to come into operational service early in 1942. The He 177 is actually a four-motor monoplane, but for identification-purposes it "can be considered a two-motor type. The four 1,150 h.p. Mercedes-Benz DB.601 motors are combined into two power units, each driving a single four-blade airscrew. Each pair of motors, mounted side by side, arc termed a 1)B.606 unit. Although liquid-cooled, they have nose radiators in the manner of the Ju 88, so that THE HEINKEL He I 77 (Provisional silhouette) externally they appear to be two large-diameter radials. The He 177 is a mid-wing monoplane—unlike most other German aeroplanes. It has a large single fin and rudder somewhat like that of the He 115. Originally a form of retractable wing-tip was provided to increase the wing area for take-off, but this now seems to have been abandoned. Armament is a cannon in the nose, another in the tail and defensive gun positions under the fuselage. Heinkel lie 177s were reported to be among the aeroplanes which bombed Belgrade, and one crashed behind the Russian lines early in the campaign. Their production was probably retarded by the heavy losses of the Luftwalfe in Russia, which caused great efforts to be put onto the output of the older types which could be turned out quickly. The following details are approximate:— Dimension Span,s.— 103 ft. 4 ins. length, 67 ft. 3 ins. height, 18 ft. 2 ins. wing area, 1,660 sq. ft. aspcct ratio, 6.2.

Points of Recognition.— Has the appearance of a two- motor mid-wing monoplane with very long nose and tail angular single fin and rudder. CIVIL IDENTIFICATION—LV THE DEWOITINE D.338 u sfli Ac- J IBO N E DEWOITINE D 338 air transport aeroplane was in this country when France collapsed in 1940 and remained here.With the Bloch 220 the Dewoitinc 338 was the main type of landplane used by Air France from about 1937. It was used on the London—Paris service, on the French West African routes to Dakar, and on the French Far East routes, as well as on the Air France services in South America. This type is still used by Vichy France ami a recent photograph in*' L'lllustration "shows a D.‘k>8, with the name** Air France *'and French civilian markings, which had flown from Vichy to Oudjda in Algeria on Dcc. 7 for the opening of the new railway across the Sahara. The Dewoitinc D.338 (three 650 h.p. Hispano-Suiza 9V motors) has accommodation for a crew of three and 24 passengers. It was developed from the original Dewoitine “ Emeraude," The American who was responsible for the sound-proofing of the Douglas DC-3 was specially commissioned to do the same for the D.338 and the Bloch 220. The D.338 is of all-metal construction with stressed skin covering. In the air this aeroplane emits a great noise, alike flight oi Harvard Dimensions. s.—Span, 96 ft. 4 ins. length, 72 ft. 7 ins. height, 18 ft. 3 ins. wing art*a, 1,065 sq. ft. aspect ratio, 8.68.
