"GILLETTE FALCON". This much-modified Miles M.3B Falcon Six (L9705) was converted at Woodley, Reading, in 1944 to take scaled-down, knife-edge main- and tailplanes in order to provide data for the ill-fated 1,000-m.p.h. Miles M.52 research project (Air Min. Spec. E.24/43). These new surfaces were of highly polished wood. First flight, 11/7/44. Fate unknown.

NINETEEN RWD-10s lined up on Mokotow (Warsaw) airfield in 1937 on the occasion of the handing over to Polish aero clubs of 129 training aircraft by the purchasers - LOPP and public organisations. Behind are RWD-8s and RWD-13s. Prototype RWD-10 (SP-ALC) with a 120-h.p. Hermes IIB inverted inline was flight tested, winter 1933/34 - some fifty RWD-10s were completed when production ceased in 1935. The production RWD-10s with 110-h .p. P.Z. Inz. Junior inlines have smaller wheels and no headrest. Painted silver and red. Span 24 ft. 7 in.; length 20 ft. 4 in.; empty 770 lb.; loaded 1,045 lb.; max. speed 135.4 m.p.h.

NOT WHAT THEY SEEM. These hitherto unpublished photographs, taken in June 1943 show two of the former Canadian Pacific Airlines' fleet of Burkley-Grow Model T8P-1s. Photo: The fixed, spatted land version CF-BMW at Edmonton Airport, Alberta.

NOT WHAT THEY SEEM. These hitherto unpublished photographs, taken in June 1943 show two of the former Canadian Pacific Airlines' fleet of Burkley-Grow Model T8P-1s. Photo: With additional central fin, the floatplane CF-BQM at Aklavik, N.W.T. The B-Gs were replaced in April 1949 by Douglas DC-3s. Eight passengers, two crew; max. speed 220 m.p.h.; span 50 ft . at in.; length 36 ft. 2 in.; power two 400-h.p. P. & W. R-985 Wasp Jnr. radials. Several are still flying.

SLOTTED FLAPPERY. Another unusual Miles Aircraft research project was a High Lift (H.L.) wing for R.A.E., Farnborough. The H.L. wing was fitted to a 1939-designed M.18 - one of four constructed. The M.18H.L. was built up in 1942 and proved to have a lift coefficient of 3. The former R.A.F. serial JN703 was replaced by the company's registration (originally U-0236) latterly U.II.

SWISS GROUND ATTACK single-seater illustrated is the second prototype F.F.A. P-16, known as the P-1604. With Swiss Air Force serial J-3002 (first which crashed in 1955 was J-3001), this second prototype, also powered by 7,900 lb. s.t. Armstrong Siddeley Sapphire A.S.Sa. 6 flew for the first time on 16th June 1956 at Altenrhein. The P-16 is the first Swiss-designed jet fighter. As such it is built round the special mountain terrain and limited-length airfield considerations peculiar to Switzerland. The P-1604-02 has new shape bleed side intakes; perforated (fuselage) air brakes and a tail cone parabrake.

READER'S QUIZ. Mr. P. Hughes of Portarlington, Vie., asks us to identify this "joyriding" amphibian (VH-UNV) photographed in Australia in the 1930s. It is a Saunders A.17A Cutty Sark four/five-seater of 1929. Mr. A. J. Jackson recalls witnessing the acceptance trials of this second built Cutty Sark at Leigh on 1st February 1930 - bearing a Class B registration L-1. VH-UNV was powered by two 105-h.p. Hermes II inlines. Span 45 ft.; length 34 ft. 4 in.; empty 2,246 lb. ; 3,200 lb. Max. speed, 150 m.p.h. Crashed, 5/4/38, Queensland.
