The Port Elizabeth Club: On the left of Lady Heath is Major Miller, who is prominently associated with civil aviation in South Africa, and has helped in the formation of the clubs by flying his own D.H. "Moth," and raising funds. On the right is the Lord Mayor of Port Elizabeth, then comes Capt. Swann, the Club's instructor, and finally, Mr.Hurch, President of the Club. In the background is the nose of the Westland "Widgeon."

With the South African Clubs: Lady Heath performing the christening ceremony of the Port Elizabeth Club's machine, the Westland "Widgeon." It was christened "The Lady Heath." The Lord Mayor of the town is seen third from the left.

THE ARMSTRONG-SIDDELEY ABROAD: Successful Fokker-Armstrong Siddeley combination. C.VI reconnaissance machine, which is fitted with the 385 h.p. "Jaguar."

SIR ALAN COBHAM AT MALTA: Our picture shows Sir Alan's Short all-metal "Singapore" flying-boat (Rolls-Royce "Condor" engines) in Valletta Harbour, prior to resuming the flight to Africa on January 21, after an enforced stay of over five weeks.

AN AVRO TORPEDO BOMBER: Three views of the "Buffalo II" with Napier "Lion XA." Special features are the extremely "clean" nose and the slot-and-aileron control. The wings are swept back, and are designed to fold. The performance is believed to be very good.

HINKLER'S FLIGHT TO AUSTRALIA: On the left, the "Great Little Man" is seen at work on his engine. On the right a "close-up" of the special vice Hinkler has made. This fits on an engine bearer, and enables work, such as adjusting a tappet rod or dismantling a sparking plug, to be carried out with convenience. The short air intake pipe has, where it joins the carburettor a "choke plate" which Hinkler uses for starting, in place of the usual rag. The "Avian" bristles with special "gadgets" thought out by Hinkler.

HINKLER'S FLIGHT TO AUSTRALIA: Two views of the special "K" type jury strut used by Hinkler for folding the wings of his "Avian". The photograph on the left shows the "K" strut in place, while on the right it is seen partly folded. A single bolt in the centre is undone, and the two halves of the "K" strut then fold into lower and upper wing respectively, where they are housed in slots in such a way as to fair in with the wing surfaces.

SNAPSHOTS FROM SOUTH AFRICA: On the left are Lady Heath, Mr. Brian Russell and Sir James Heath standing before the former's Avro "Avian," which was in course of erection at Young's Field, the aerodrome outside Cape Town. On the right is Lady Heath tightening up the propeller, whilst other energetic workers are seen under the machine and in the rear cockpit.

This is the Avro "Avian" which A. V. Roe and Co. have supplied to the Hampshire Aero Club. It is fitted with the new undercarriage which is automatically swept back when the wings are folded, bringing the machine nearer the ground. Thus the engine is more accessible for inspection and adjustment. Also a good deal of weight is taken off the tail skid, thereby facilitating the manoeuvring of the machine. These photographs were taken at Woodford Aerodrome, Cheshire, after the machine had been tested.

AN "AVIAN" IN SOUTH AFRICA: In this interesting group discussing the unpacking of Lady Heath's "Avian" at Cape Town will be noticed Sir James Heath (with walking stick) and Lady Heath, whilst stroking the glossy neck of the horse is Col. Henderson. The lady rider is Miss Jute, of Johannesburg, who learned to fly with Col. Henderson and was ready to go solo within a week.

HINKLER'S FLIGHT TO AUSTRALIA: This view of the "Avian" with wings folded gives a good idea of the way in which Hinkler's special type of undercarriage lowers the front of the machine and makes the "Cirrus" engine very accessible. Also the wheels move aft and relieve the tail skid of nearly all its load.

SEVEN-AND-A-QUARTER MILES HIGH: Comm. Donati, the Italian pilot, who recently attained an altitude of 11,852 m. (38,886 ft.) on an Ansaldo-Dewoitine monoplane fitted with an Alfa-Romeo "Jupiter" engine. He is seen wearing his special flying kit and "Salvator" parachute.

THE SHORT "CALCUTTA" THREE-ENGINED FLYING BOAT: Some constructional details. A section of the rear spar of the top centre-section is shown in 1, with its steel fitting for strut and lift wires, etc. 2, shows a section of the top rear spar. Note the laminations which reinforce the spar at point of attachment of fittings. Built-up compression struts are used, the end of one being illustrated in 3. The spars of the lower centre-section differ slightly in construction, as shown in 4. The curved angle-section piece conforms to the cabin roof, through which this spar passes. The attachment of the raked struts which run from lower plane at engine supports to chine, meet the latter as shown in 5. The two petrol tanks are housed in the top plane, and are of the form shown in 6. Details of the tank supports, incorporating rubber buffers, are shown in 7 and 8.

THE SHORT "CALCUTTA": Plan of the passenger accommodation.

THE SHORT "CALCUTTA": On the left, a view inside the luggage compartment, showing the general construction, the special hatch which also serves as an emergency exit, and the tubular steps. When open, the hatch is kept raised by the two tubes shown folded in their clips. On the right, a portion of the cabin, showing construction, and, right, the finished cabin covered with material. Below is a double seat, with the neat folding tables provided for each passenger.
