View from above of the Northrop Monoplane. This photograph shows the machine fitted with tractor airscrew.

The Northrop "All-Wing" monoplane (pusher version) in flight. One cockpit covered in.

THE NORTHROP "ALL-WING" MONOPLANE: This front view of the "pusher" version illustrates very clearly the tapering of the thick centre-section into the wings proper, and also shows the three-wheeled undercarriage.

"PEACEFUL PENETRATION": One of the latest Junkers type F.13 monoplanes has been registered in this country, and is now on a tour. Of the same general type as the famous "Bremen," this machine has a Junkers L.5 engine and seating accommodation for four passengers. It is intended for use by the wealthier class of private owner, or for air taxi work.

THAT GENTLE TOUCH: Miss Slade puts her Moth down at Desford, but the wind nearly takes it off again for her.

FOR THE IRISH FREE STATE: A most successful acceptance test flight has been accomplished with the first Vickers "Vespa IV." Army Co-operation aircraft, fitted with an Armstrong-Siddeley "Jaguar IVc" engine shown here, for the Army Air Corps of the Irish Free State. The performance put up by the machine was 135 m.p.h. at 15,000 ft.

THE AUTOGIRO: The Auto giro is now to be seen at nearly all the flying meetings, and never fails to create great interest.

Phoenix II, G-AAIT, at Mousehold, where it served as the company's own aircraft.

Another type of machine, the Latecoere 28, used by the Cie. Generale Aeropostale.

NEW ALL-METAL TRAINING MACHINE: After undergoing tests at Martlesham, the new Avro "Trainer" has now gone into production, and a batch of machines is being built. Several have also been ordered for use in the Dominions and abroad, some for air survey work. The machine can be fitted with the Armstrong-Siddeley "Mongoose" engine (standard) or with the "Lynx" for special purposes, such as operating from aerodromes situated at a considerable altitude. A detailed description will be published next week.

NORWICH AIR DISPLAY: The Klemm (40-h.p. Salmson) light monoplane.

The little Klemm monoplane with Salmson engine was much in evidence, and is here seen flying low, piloted by Flying Officer Alliott. Later in the day one of the "Moths" charged the Klemm, which was somewhat "bent."

SOME "MOTH THREE" DETAILS: In the centre, the joint at the port front spar attachment, and on the left the joint dissected to show the construction. On the right the top end of the compression strut of the undercarriage, showing the swivel joint and stop for the strut when rotated to act as an air brake.

THE MOTH "THREE": On the left a sketch of the steerable tail skid, and on the right details of tail trimming gear.

The Mounting of the "Gipsy III" Engine in the "Moth Three" makes use of rubber pads in trunnion supports to damp vibration.

THE FLYING TEST: W. B. Rich are running their Moth on their mineral oil to give practical proof of its ability to do the job properly.

THE FLYING TEST: Last week we showed this Moth, and through a printer's error it was called the property of W. B. Rich. It does, of course, belong to W. B. Dick, the makers of the well-known "Ilo" brand lubricating oils, and their Moth is being used as a "test shop" for the mineral oil which is advised as being the most suitable for all such machines.

THE LEADER: Mr. Nigel Norman flying down the line before leading the tour to the Continent.

APPROPRIATE LETTERS: The machine on the left belongs to Mr. Ivor McGlure, of the A.A., while that on the right is Mr. Runciman's, and is the first private owner's machine fitted with the Amplion wireless gear we described on November 21 last year.
