DE LUXE TRAINING: The Hawker "Hart Trainer" (Rolls-Royce "Kestrel" engine) is the most recent addition to the series of training aircraft.

A FORMATION OF AIRCRAFT TYPES USED FOR INSTRUCTION AT THE CENTRAL FLYING SCHOOL: From left to right, Gamecock, Atlas, Moth, III.F, Avro-Lynx, Siskin and Bulldog.

SCENES AT HESTON: Some of the commercial aircraft which were on view - ABGK, Lockheed "Vega"; ABLI, Spartan Mailplane; ABEF, Ford; ABDC, Junkers; ABDH and ABFV, "Puss Moths."

Flt. Lt. D. V. Ivins boarding his privately-owned Bristol Fighter (Hispano).

THE ATLANTIC CIRCUMNAVIGATED: Two views of the Dornier Do.X moored off Calshot. These pictures give a good idea of the height of the propellers above the water line, where they are well protected against spray. The use of the lower wing stumps as boarding platforms is also well brought out.

AN EARLY "PUSHER": One of the Bristol "Box Kites" with Gnome rotary engine, on which many early pilots were trained.

The start of the first heat for the Race at Skegness: (Left to right) "Avian," "Cadet," "Avian," "Spartan," "Widgeon" and Autogiro - the last, in its first race.

"LADY LINDY'S" LOCKHEED: Miss Earhart's Lockheed "Vega" monoplane in the field outside Londonderry, after the Atlantic crossing.

The Lockheed "Orion" used by Swissair on its high-speed services.

WITH UNDERCARRIAGE RETRACTED: One of the Lockheed "Orions" of the "Swissair" company as it appears in flight.

Squadron "V": A fine piece of formation flying by No. 40 (Bomber) Squadron.

Line Abreast: Among the clouds on a stormy day.

"Squadron, Right wheel": No. 40 (Bomber) Squadron in squadron formation.

BRITISH AIRCRAFT IN SPAIN: As previously reported in "Flight," a Vickers "Vildebeest" torpedo carrier was recently delivered to the Spanish Government at Madrid - the first of an order of 26 machines. Our picture shows the machine at Madrid, when a successful demonstration was carried out by Mr. H. W. R. Banting.

A MODERN TRAINING MACHINE: The Avro "Tutor," or 621, with Armstrong-Siddeley "Lynx" engine, is a worthy successor of the 504.

HANGING ON THE ANTI-LIFT WIRES: Captain Hubert Broad doing inverted flying on one of the new "Tiger Moths." The first of a batch of these machines have already been delivered to the R.A.F. Flying Training School at Grantham.

A view of the new Avro "Cadet" which Mr. H. A. Brown threw about in an amazing manner. Six of these aircraft have been delivered to the Irish Free State for training.

SAFETY IN THE AIR: His Royal Highness the Duke of York inspected the aerodrome building at Croydon, and the Handley Page "Horatius," on the occasion of the Inauguration of the Air Safety Section of the National Safety First Association on May 5.

The Annual Display of the Scottish Flying Club was held at Moorpark Aerodrome, Renfrew, on May 21, 22 and 23 in "some" rain. "Heracles," the Imperial Airways H.P.42, flew up so that visitors were able to have joy rides in a modern large aircraft. On Saturday there was a display by No. 602 (City of Glasgow) (Bomber) Squadron, A.A.F., in their Westland "Wapitis."

The winner's "Puss Moth" (Gipsy III) arrives in the rain at Heston.

WITH THE POWERS OF NEMESIS: Capt. A. G. Lamplugh, Underwriter and Principal Surveyor of the British Aviation Insurance Co., Ltd., is here seen at Heston with his company's "Puss Moth." Everyone was glad to see him walking about again after his accident. He looked very fit, although it will be seen that hoped that he still has to rely on a strut for his "undercarriage."

THE LATEST PASSENGER-CARRIER: The cabin of the Airspeed "Ferry" has seats for 10 passengers, who all get an excellent view.

THE FIFTH AND LATEST: The Blackburn Iris "family" has reached its fifth descendant with the "Iris V" shown here in flight. This is by far the most powerful of these Blackburn boats, being driven by three Rolls-Royce "Buzzard" engines of more than 800 h.p. each. As a result of the extra power the performance is greatly improved, and the machine will maintain flight with any one of the three engines stopped.

H.E. The Viceroy and Lady Willingdon arrived by aeroplane at Peshawar on the 16th April, to install the new Governor of Province (Sir Ralph Griffiths), and to inaugurate the new Legislative Council. In the photo are seen Lord Willingdon, shaking hands with Lady Griffiths. Lady Willingdon has just descended from the Avro 10 and is going to shake hands with Sir Ralph Griffiths (Chief Commissioner of the North-West Frontier Province and Governor Designate).

THE MAKHONINE MONOPLANE: View of the machine with wings extended, as for takeoff and landing.

THE MAKHONINE VARIABLE AREA MONOPLANE: This view shows the wing area reduced almost to its minimum, as it would be in the high-speed condition.

THE MAKHONINE WING: This sketch is purely diagrammatic, in order to show the principle, and does not correspond closely with the actual wing.

THE "FLYING CARPET": Richard Halliburton and Moye Stephens, who are on a World Tour, flying over the Taj Mahal.

American interest in the cabin Autogiro at Hanworth: (Left to right) - Larsen, H. Pitcairn, A/M. J. G. Weir, Senor de la Cierva, T. Ray, R. A. C. Brie.

AERODROME RACING: Realising the fascination of watching aeroplanes racing around a course on the aerodrome, Sir Alan Cobham has included this item in his programme. Here are seen a Southern "Martlet" and a Comper "Swift" fighting for first place.

THE HORNET'S NEST: AN AERIAL VIEW OF THE AIRCRAFT CARRIER "COURAGEOUS." THE MACHINES RANGED ON THE FLYING DECK INCLUDE FAIREY "FLYCATCHERS" AND IIIF'S. NOTE THAT BOTH LIFTS ARE DOWN, PRESUMABLY TO FETCH MORE AIRCRAFT.

SARO "CUTTY SARKS" FOR CHINA: Two of these machines were shipped recently. They are fitted with two Armstrong-Siddeley "Genet Major" 7-cylinder engines, which give a materially improved performance; extra fuel tanks have been fitted, giving a maximum duration of 7 hours.

A NEW SARO "CUTTY SARK": Fitted with a direct-drive Armstrong-Siddeley "Lynx" engine, this machine has been equipped with extra tanks and special instruments, and is being flown by the Japanese pilot Yoshihara from San Francisco to Japan - as previously reported in "Flight."

A FOREIGN VISITOR: The Raab-Katzenstein (Siemens) which Herr Max Behland has brought over to Heston. It is understood that he will be giving some acrobatic displays, a form of flying at which he is particularly experienced.

FITTED FOR "BLIND" FLYING: The Hawker "Tomtit" (Armstrong-Siddeley "Mongoose" engine) has a hood over the rear cockpit, used for teaching flying entirely by instruments.

The "scratch" man, F/O. E. C. T. Edwards, taking-off on his Hawker "Tomtit" (Mongoose III).

FROM FINLAND TO THE CAPE IN A JUNKERS "JUNIOR": As previously recorded in "Flight," Capt. V. E. Bremer, the Finnish airman, recently flew from Finland to Capetown in a Junkers "Junior" (Armstrong-Siddeley "Genet"). Our picture shows Capt. Bremer with his machine about to leave Helsingfors - actually, he flew the "Junior" and did not haul in as shown! During this trip he made two fine non-stop flights, from Naples to Tunis, across the Mediterranean, and from Cairo to Wadi Haifa - a distance of 750 miles in 7 hours.

THE "VALETTA" LAND UNDERCARRIAGE: It picks up on three of the four points used in the float undercarriage, the outer rear support being idle.

THE TAIL WHEEL: This is of the castoring type, and is centred by the rubber cords.

LANDPLANE AND SEAPLANE: The Short "Valetta" (Bristol "Jupiter" engines) has now been fitted with a wheel undercarriage, and has been flown as a landplane. A view of the machine as a seaplane is included for comparison.

UNUSUAL BRACING: This front view shows the arrangement of the rigid strut bracing, which distributes landing loads in an unusually complete way.

AT THE ATHENS AERO SHOW: The de Havilland "Gipsy Moth" which was one of the British exhibits at the recent International Aero Show at Athens.

"Moths" of the Aero Club du Katanga outside the hangars at Elisabethville, in the Belgian Congo.

ENDURANCE: Mr. C. W. A. Scott, who flew from England to Australia in 8 days 20 hr. 47 min. in his "Gipsy Moth."

Mr. J. Grierson, "Moth" (Gipsy I), arrives at Heston, second, in still heavier rain.

Mr. G. Baillie, the third arrival. His "Moth" (Gipsy I) was fitted with a Standard wireless set by means of which he was able to get the weather reports broadcast from Heston during the race.

SOME EARLY AEROPLANES: 3. THE MAURICE FARMAN "SHORTHORN" HAD NO FRONT ELEVATOR. BOTH TYPES WERE FITTED WITH RENAULT ENGINES.

THE FARMAN 250: The view shows the clean lines of this new passenger and mai plane.

THE SCHMEIDLER VARIABLE WING: Three-quarter rear view of the experimental machine.

THE SCHMEIDLER VARIABLE WING: Diagrammatic Plan View of the arrangement of the wing. The trailing edge is pivoted at the outer end and housed in the main wing.
