Flight
SHADES OF OLYMPUS! Example of early aircraft exhibited at previous Olympia Aero Shows. The Bristol Scout (80-h.p. Gnome) of 1914, perhaps the first of the modern, highspeed Military machines. It played an important part in the Great War which opened that same year.
Junkers K.47 low-wing monoplane with twin tail (Bristol "Jupiter" engine) on which Herr W. Neuenhofen won third place and ?20 in the International Aerobatic Competition.
The Hawker Stand has the distinction of exhibiting three machines never hitherto seen in public: The "Tomtit" training machine, the "Hart" day bomber recently ordered in quantities for the R.A.F., and the "Hornet," believed to be the world's fastest single-seater fighter.

ACCOMPLISHED! Southern Cross monoplane makes the final landing of the Australia-England flight at Croydon, July 10.
DISTINGUISHED VISITORS AT FILTON: On July 17 the Bristol Aeroplane and aero engine works were visited by the Infante of Spain and M. Robert Esnault Pelterie, one of the pioneers of French aviation. The Infante, who is one of the finest Spanish pilots, made a flight in a Bristol "Bulldog," and made a perfect three-point landing. In the photograph are seen, on the right, from left to right: Don Alfonso, Senor Carlos de Quiros, Mr. C. F. Uwins, and M. Robert Esnault Pelterie.
EVENT 9. LOW ATTACKS: A demonstration of low attacks was given by Day Bomber and Fighter Squadrons. Here are seen three Bristol Bulldogs of No. 3 Fighter Squadron

Below, they are nearing the ground; the two on the left collided, and one released another, emergency, 'chute (which can be seen opening) and thus avoided an accident.
AIRCRAFT IN THE KING'S CUP: S.E.5A (120-h.p. "Airdisco" and 200-h.p. "Viper").
IN THE DISPLAY: Although a War Veteran, the Bristol Fighter, modernised and fitted with slots, is still seeing service in the R.A.F.
