N.B.—The performance figures apply to the 220 with HispanoSuiza12Ybrs .•ngincs. Nogues and Balizuc, who are technical directors of Air-France, flew in the machine, which might indicate that Air-France is interested in a civil version of the aircraft.The following description will apply to both the 220 and 221. The inner sections of the main planes are ofparallel chord, but the sections outboard of the junction of the bracing struts and the wing are tapered inplan form. Four fuel tanks are carried within the wing. The fuselage is of rectangular section, the maximum heightbeing about 8 ft. and the maximum width nearly 6 ft. In the forward portion of the fuselage is a gunner's cockpitwith mounting for twin Lewis guns, bomber's position, navigator's and mechanics' quarters, and an enclosed cabin,with dual control for two pilots. The aft portion of the fuselage contains the wireless operator's position and agunner's position on top of the fuselage. Bomb racks over 16 ft. in length for a normal load of 4,850 lb. of bombsare mounted within the fuselage. Actually a bomb load of 8,818 lb. can be carried if necessary. An undercarriageof wide track, using differentially controlled Messier brakes, is used. The tail wheel is of the swivelling type. ; The S.P.GA. 20 M.4 '""PHIS " multiplace de combat," manufactured by theSociety Provencale de Constructions Aeronautiques, possesses a number of interesting features, the most striking of which are probably its twin fuselages. The low canti- The pilots' cockpits are in tandem and are fitted withdual controls. Ait of these cockpits is a position for a downward firing gun. This position may also accommo-date the photographic equipment and bomb racks. The two engines are carried in the noses of the twin fuselages,in each of which a gun ring is fitted ait of the trailing edge of the wing. Two " droppable " fuel tanks arecarried, one on each side of the central nacelle. Either Lorraine 18 Kd. 650-h.p. engines or Hispano- Suiza12 N brs. engines of the same power may be fitted.

Ceiling 24,600 ft. lever wing is in three sections, the centre section connect-ing the two fuselages. In the middle of the centre section is a nacelle which houses the pilots and a navigator-gunner,who is also the bomb aimer when the aircraft is equipped for bombing. UNORTHODOX : The Lockheed " Alcor," similar in general design to the " Vega," has two " Menasco " engines mounted crankcase to crankcase across the nose of the fuselage. The resistance is claimed to be about half that of the normal radial engine installation. MILITARY LOAD : The Breguet 27 is not of ni>w design, but during the past two or three years ithas been continually improved. Here we see it in its latest form—fitted with a Gnome-Rhone " Mistral Major " 14 KRSd supercharged two-bank radial, which gives well over 1,000 h.p. for take off, and israted at 815 h.p. at 2,390 r.p.m. at 7,150 ft. As a reconnaissance machine or as a bomber, the " 27 " is equally efficient. In the latter form, a bomb load of about 1,840 lb. may be carried. The perform-ance figures for the Gnome-Rhone-engined version are not available for publication, but when the " 27 " is fitted with the Hispano-Suiza 12 Ybrs water-cooled engine of 850 h.p., it has a maximum speed ofabout 186 m.p.h., climbs to 16,375 ft. in about 9 minutes and has a ceiling of over 30,000 ft.—not, of course, carrying the maximum permissible bomb load. The Breguet 27 A2, fitted with a 500-h.p.Hispano-Suiza engine, is a standard type in the French Armee de 1'Air. 202 'Hi..
