Looking forward into the pilot's cockpit: The pilot's seat can be seen on the port side, with the throttle levers and mixture controls by his right hand.

This view of the centre portion of the "Knuckleduster" shows the braced internal structure. The bunks are for the crew.

A view aft through the pilot's cockpit : Note the "tumble home" of the corrugated outer skin plating.

This photograph of the Gloster F. 7/30 are of particular interest, because a number of these day-and-night fighters, with 605 h.p. Bristol "Mercury" engines, have been ordered by the Air Ministry. The picture was taken by Flight's photographer from a Hawker "Hart" flown by Flt. Lt. P. W. S. Bulman, who made a rendezvous with Flt. Lt. P. E. G. Sayer in the F 7/30 midway between Brooklands and Gloucester. Two of the F. 7/30's guns are in the fuselage and two under the wings.

REGAL ENTHUSIASM. H.M. the King of the Belgians attended the recent display of the Belgian Air Force at Evere. He is seen with Queen Astrid after alighting from the Fairey "Fox" in which he had flown.

The comparative silence of the Gloster "Gauntlets" of No. 19 (F.) Squadron was generally commented upon when they carried out squadron air drill.

Juvenile, but nevertheless critical, interest was not lacking. The picking-up of messages by the six "Audaxes" of No. 26 (A.C.) Squadron certainly met with approval.

FOR DUTCH COLONIAL SERVICE: A Rolls-Royce "Kestrel-"engined Fokker C.X two-seater of a type which is being supplied to the Dutch Colonial Air Force. The particular machine shown here has a 525 h.p. "Kestrel IIS'' but the production models are receiving "Kestrel Vs" of 600 h.p. At the critical altitude a speed of 205 m.p.h. is attained.

NOT LESS THAN 250 M.P.H.: The "Fantome" entered by the Fairey company for the Belgian fighter competition. Armament consists of a 20 mm. canon firing through the airscrew shaft of the 860 h.p. Hispano-Suiza 12Y. brs. liquid-cooled engine, and four Browning guns. Flt. Lt. C. S. Staniland, Fairey's chief test pilot, was flying the machine when this Flight photograph was taken.

Water-cooled representatives: The Fairey "Hendon" heavy bomber on the left has Rolls-Royce "Kestrel" engines, while the "Fantome" on the right has the Hispano-Suiza moteur canon.

INVERSION AT CLOSE QUARTERS. Something the Hendon Display spectators did not see - what the inverted Ano "Tutors" of the Central Flying School look like from another machine only a few yards distant.

MORE THAN MEETS THE EYE: This innocent-looking D.H. "Tiger Moth" is actually the wireless-controlled target machine, designated the "Queen Bee," the existence of which was kept an official "secret" until a few days ago. Note the connection at the side of the fuselage for catapult work.

Although a biplane and a cabin machine, the "Hornet Moth," as this view shows, is clean aerodynamically. The undercarriage compression leg is an oleo type by Dowty, and the sloping windscreen is a curved one-piece one of cellon.

The D.H. Hall Mark: A fine view which shows the heavily tapered wings of the "Hornet Moth," a distinctive feature of all modern De Havilland aeroplanes.

The amount of windscreen visible in this head-on view of the "Hornet Moth" shows the success of the designer's efforts to provide the pilot with a good outlook.

THE WESTERN FLEET. Starting operations with a single machine at Filton aerodrome in 1929, Mr. Norman Edgar's fleet now consists of three D.H. "Dragons," two "Puss Moths" and a "Gipsy Moth." Additional and faster machines are to be acquired in due course for service extensions detailed in this issue.

Cooling themselves synthetically in the shade of a "Leopard Moth" are (left to right), Miss Fontes, sister of Luis Fontes of motoring fame, who was second in the Grosvenor Trophy Race, Mrs. Macdonald, Mrs. Battye, Mrs. Paterson, Mr. Roy Harben and Mr. Harold Perrin, Secretary of the Royal Aero Club, who appears to be blowing on his ice, presumably to raise its temperature before eating it.

SENIOR AND JUNIOR. Units of the Fleet Air Arm gave a wonderful exhibition of formation flying during their fly-past at the review by the King of his fleet. This is how the Blackburn "Baffins" of No. 810 (T.B.j Squadron appeared from one of the lower decks of HMS Glorious. A sister-ship, the Courageous, is on the left of the picture.

Picturesque, if not exciting - sixteen Irvin parachutes, carrying 200-lb. weights, being dropped from Vickers "Virginias" of the Home Aircraft Depot.

The rubber-driven "Comper Swift" model with which Mr. H. G. Lambert won the Flight Challenge Trophy at the Northern Heights Model Flying Club's Rally last Sunday. Results were judged both on appearance and performance. The model is of the machine which finished second in the 1932 King's Cup Race, entered by H.R.H. the Prince of Wales and flown by Flt. Lt. E. H. Fielden.

ON THE ROAD: The fuselage of a new and experimental Boeing bomber which has been entered in competition with other types at Dayton, Ohio. It will be known as the Boeing 290. Four "Hornet" engines, driving constant speed airscrews, are fitted. The span is approximately 100ft. and the gross weight about fifteen tons. A speed between 200 and 250 m.p.h. at 10,000 ft. is demanded by the specification.

A BRITISH "POU" FLIES. The Flight photographs above show Mr. Appleby with his Pou-du-Ciel (special 10 h.p. Ford engine) and (in circle) during one of his initial "hops" at Heston a few days agp. On the right is the "Pou" built by Mr. Philip Priest of Huddersfield, with the help of his cousins, Allen, Kenneth, and Geoffrey; its behaviour during experimental taxying has been promising. At present it is fitted with a Douglas motor cycle engine, but awaits a special Scott unit, as does the Pou built by Messrs. C. Brooke, A. Morton and F. Lawton, also in Huddersfield. Mr. Priest says that he and Mr. Brooke have each spent about ?30 on their "Pous," so, unless the matter of a C. of A. proves troublesome, the total cost, with engine, should be about ?75 in each case.

THE "POU DU CIEL" which Mr. S. V. Appleby is building at Heston is progressing fast, and will shortly be taking the air. The engine, as announced in Flight of March 28, is a four-cylinder watercooled unit developed by Sir John Carden. Basically it is a 10 h.p. Ford car engine, with a welded steel-plate sump and a modified light-alloy cylinder head. In this form the output is expected to be 30 h.p. at about 3,400 r.p.m. Engine and fuselage are shown in this sketch

Lt.-Cdr. C. W. Phillips, R.N. (retd.), who won the Grosvenor Trophy in Mr. Lindsay Everard's "Moth" ("Gipsy III."). The engine is historical, as it is the one which the late Miss Winifred Spooner purchased for her Breda machine for competitions in Europe.

The Bristol "Aquila" engine was seen at Hendon for the first time in this Bristol "Bullpup."

SPEED WITH A DIFFERENCE. The "Crusader" AG-4, which is produced by the American Gyro Co., of Denver, Colorado, seats four people and cruises at 210 m.p.h. with two 156 h.p. Menasco engines. A larger version will carry five passengers and a pilot at a maximum of 237 m.p.h. In this case the two engines will be Menascos of 210 h.p. each.
