GEORGE & JOBLING biplane (A.E. George & Jobling, Smith St., Newcastle-on-Tyne, Motor Engineers)
A.E. George, a racing motorist, acquired the Voisin 'Bird of Passage' but abandoned it after a crash at Shellbeach. He subsequently decided to build a machine of his own design, which he was ready to exhibit at the Olympia Aero Show in March 1910. On 13 May 1910 he flew straights up to 130 yards at Eastchurch and, by the end of May, had made twenty flights. At the end of August George had passed the tests for his pilot's certificate on it at Eastchurch. By October the machine was moved north, but on 6 October 1910 at Gosforth Park, Newcastle damage occurred. The machine had flown 300 miles, with a longest flight of eighteen minutes and, although reported to have been repaired and ready to fly again, there was no further report that this took place.
This well designed pusher biplane used bamboo for the booms, which were to be replaced by steel tube. It had front and rear elevators, a single rudder and side panels in the front booms. Midgap ailerons were fitted to the front outboard interplane struts, together with warping extensions to the top wings for lateral control. Small side curtains were also fitted. All controls were operated by the hand-wheel and movement of the control column.
The undercarriage was made of steel tube, and the twin skids could be lowered to aid the passage of the machine over rough ground when alighting. A steerable tailwheel and wing tip skids were fitted.
Power: 60hp Green four-cylinder inline, water-cooled driving through chain a 9ft dia. G&J propeller at 2:1 reduction on a shaft above the engine, the whole being mounted on a subframe. The radiators were of surface type forming part of the lower wing.

George and Jobling Biplane
The George and Jobling Biplane was designed by A. E. George and was built by George and Jobling at Newcastle in 1910. The machine was a single-seat pusher with a four-cylinder 60 h.p. Green engine which drove a 9 ft. propeller mounted on a fixed shaft above the engine, to which it was chain-geared. Exhibited at the Olympia Aero Show of 1910, other unusual features embodied in the design were the hollow struts and spars, balancers for lateral control mounted mid-way between the wing-tips and the sharp angle at which the skids on the undercarriage and wings were mounted to enable the aeroplane to clear ditches and other obstructions on the ground. Control surfaces comprised a forward elevator, mid-gap Curtiss-type ailerons and a single rudder mounted below a fixed tailplane. The machine made several successful flights at Gosforth during the summer of 1910. Span, 30 ft. Length, 31 ft. Wing area, 325 sq. ft. Weight empty, 662 lb. Weight loaded, 862 lb. Maximum speed, 48 m.p.h.

THE SECOND OLYMPIA AERO SHOW.
AEROPLANES.
G. and J.
BRITISH-BUILT biplane of 30 ft. span, the supporting surface of the main planes being 325 sq. ft., while the total surface, including tail, elevator and ailerons, is 438 sq. ft. A feature of this machine is the triplicate control, whereby both rudder, elevator and ailerons can be operated by one hand without any one motion interfering with any other. The rear tips of the top plane are extended and flexible, and coupled to the ailerons, so that lateral stability is governed both by the entering edge of the aileron and the trailing edge of the flexible tips.

BIPLANE designed by A. E. George and principally remarkable for the fact that all the struts and spars are hollow. The outriggers that carry the elevator and tail are made of bamboo. A curious form of combination wheel and ski chassis has been adopted, the skis being wholly in front of the wheels and normally inclined upwards; their object is mainly to assist the machine over holes and small ditches. A very interesting feature of the machine is the method of mounting the single chain-driven propeller upon a stationary axle, which is held by adjustable tubular steel struts upon the engine bearers. This stationary axle lies immediately above the engine, and the mounting of the propeller is thus entirely independent of the framework of the machine.
