First photograph to be released of a Boeing B-52A, with underwing tanks: Note the wide angle of depression in the tail turret, which houses four .5-in. machine guns. This can be either manually- or radar-directed.
SAAB J-29F. Latest version of the SAAB 29 fighter to be delivered to the Swedish Air Force is the 29F, with modified and lightened outer wings and an afterburner on the Ghost turbojet. All-round performance has thus been improved, and particularly rate of climb. The new outer wing was first tested in December 1953, and the afterburner flew for the first time in March 1954. In addition to a batch of pre-production "F"s now on delivery, a number of standard J29s will be converted to the new standard.
Salient features : A tubby mid-wing monoplane , the SAAB 29 has a moderately-swept wing, rounded delta tailplane and a very distinctive cut-out at the jet exhaust. Cockpit is set well forward towards the round nose intake. The wing of the "F" has sharp sweep on the root panels and moderate sweep on the rest of the inner wing. Outboard of the wing fences the leading edge is extended forward, although retaining the same degree of sweep. Tips are rounded. The fin is square-cut with taper on the leading edge. Main undercarriage wheels retract into the fuselage, and the nosewheel backwards.
SAAB J-29F. Data: Manufacturer: SAAB Aircraft Co., Linkoping, Sweden. Power: one de Havilland Ghost turbojet of 5,000-lb. thrust plus afterburning. Accommodation: single seat. Dimensions, weights and performance: no data available.

This Cessna 180, N3100C, is equipped for "sky-shouting" but the loudspeaker is concealed in the luggage compartment. It is owned by the U.S. Border Patrol. The "shouting" can be heard from 3,000 ft.
Sixth Viscount for T.A.A., VH-TVF, has "slipper" tanks outboard of the engines. Each holds 145 gallons and together they increase range by 255 miles.
LOCKHEED Y1C-12. Produced in 1931 , the "one-off" Y1C-12 "Army Vega" was a four-seat cantilever high-wing monoplane with a Pratt and Whitney R-1340-7 radial of 450 h.p. It was based on the Fokker DL-1 and was built by Loughead (later Lockheed) then a division of the Detroit Aircraft Corporation. Span was 41 ft.; length 20 ft. 7 in.; gross weight 4,402 lb. ; and top speed 179 m.p.h.
BOEING YB-40. Produced as an escort fighter for standard B-17s, the YB-40 had the heavy armament of fourteen .5-in machine guns, two of which were included in a power turret in the radio compartment upper panel. The YB-40 was a B-17F converted by Vega in 1943. It was found on trials that the YB-40 was not a success, as the heavy weight of the armament and ammunition remained about constant, while normal B-17s were lighter after dropping their bombs and had improved performance to get home. Four YB-40 conversions were made.
FLEET MODEL 21M. The Fleet 21M was a two-seat trainer built by Fleet Aircraft of Canada Ltd., a branch of American Fleet Aircraft Inc., which was in turn a division of the Consolidated Aircraft Corp. Span was approximately 32 ft .; loaded weight about 3,000 lb. This machine has been modified as a single-seater.
PARNALL HENDY HECK Mk. 2. Originally produced in 1934 to the order of Whitney Straight, the Hendy Heck appeared in production form in 1936 as the Mk. 2 - with a number of modifications compared with the prototype. Several Hendy Hecks were built to meet Air Ministry orders, mainly for experimental purposes. During the war Hecks were used for communications. An interesting feature of the design was the incorporation of slotted flaps and leading-edge wing slots. The engine was a 205-h.p. Gipsy Six 2. Span was 33 ft. 6in.; length 26 ft. 1 in .; loaded weight 2,600 lb. and top speed 170 m.p.h. Range was 620 miles at 155 m.p.h.
PILATUS P-3. Successor to the Pilatus P.2 advanced trainer supplied in small numbers to the Swiss Air Force, the P.3 is an all·metal, low-wing monoplane which flew for the first time in September 1953.
Salient features: A conventional tandem two-seat, the P.3 has a long nose resembling in outline that of the Beech Bonanza. The cockpit is long with a curved top, which includes a longitudinal metal strip. From the rear of the cockpit the fuselage line slopes sharply down. The wing, with dihedral from the roots, is square-cut and equi-tapered. The fin is also square-cut with a small dorsal fillet, and the rudder has a noticeable cut-out at its base. The square-cut tailplane is centrally mounted on the fuselage. Main undercarriage legs retract sideways and the nose wheel backwards.
PILATUS P-3. Data: Manufacturer: Pilatus Flugzeugwerke A. G., Stans, Switzerland. Power: one 240-h.p. Lycoming GO-435-C2 horizontally-opposed engine. Accommodation: two-seat. Dimensions: span 34 fl. 1 in . ; length 28 ft. 8 in.; height 10 ft. Weights: empty 2,310 lb .; loaded 3,300 lb. Performance: maximum speed 192 m.p.h.; cruising 155 m.p.h.; initial rate of climb 1,378 ft./min . ; service ceiling 18,040 ft.
DRUINE D-60 CONDOR. A typical modern French ultra-light aircraft is t.he Druine Condor two-seat, fitted in prototype form with the 60-h.p. Continental, but intended later to have a 90-h.p. unit. It is expected that the Condor will be available in kit form for group and private construction, as were the Turbi and the Turbulent.
Salient features: With pleasing lines, the Condor is a conventional low-wing light aircraft with a blunt nose and slab-sided fuselage. The propeller boss is covered by a small spinner, on either side of which are the intakes for the engine. The cabin is raised and has a curved windscreen. Wings have little taper, are square-cut, and have dihedral from the roots. The fin is tall with curved top, tapered rudder trailing edge and a small dorsal fillet. Tailplane is also squarecut and set on the fuselage top line. Main wheels are staggered outwards, and a small tail wheel is carried.
DRUINE D-60 CONDOR. Data : Manufacturer: Avions legers Roger Druine, 20, avenue de General Clavery, Paris 16. Power: 60 h.p. Continental. Accommodation: two-seat, side by side.
GLOSTER C.16/28. From time to time in future we shall be featuring in silhouette and descriptive form unusual and interesting aeroplanes of the past, in addition to new types . This month it is filling, in view of the company's impending fortieth anniversary, that we feature a Gloster aeroplane. In this case it is the Type 33, sometimes known as Goshawk. This should not be confused with the Gloster V racing seaplane, which also bore the same type number. The Type 33 was built to specification C.16/28 and serialled J3982 . It was designed to carry thirty troops or alternative load over a range of 1,200 miles. Only one was built.
The prototype was completed in January 1931 and it is interesting to note that, because the hangar doors were low, the undercarriage had to be assembled in two trenches. The aircraft was winched in and out of the hangar by way of these trenches.
GLOSTER C.16/28. Data : Manufacturer: The Gloster Aeroplane Company Limited, Hucclecote, Glos. Crew: four. Dimensions: span 94 fl. ; length approx . 78 ft. Weights: not known . Performance: maximum speed 146 m.p.h.; service ceiling 20,000 ft.; Power: four steam-cooled Rolls-Royce Kestrels each of 525 h.p.
