No practical good can therefore accrue to aviation from elaborate measurements of the wings and body of any flying thing; neither can any rule be laid down as to the extent of surface required for sustaining a given weight in the air.
The progress made by all these experiments at aviation had naturally created widespread interest, both as a matter of sport and also as indicating a new departure in the possibilities of machines of war.
The subject of aviation is admittedly one of extreme difficulty.
Henson's flying machine, designed in 1843, was the earliest attempt at aviation on a great scale.
The total number of units were, in the infantry, 28 regular battalions, I reserve battalion and 3 battalions of Frontier Guards; in the cavalry some 8 squadrons; in the artillery 9 field batteries; in the engineers 1 electro-technical and 1 auto battalion, a pioneer company and a railway operating company plus an aviation corps, or a total of about 1,200 officers and 35,000 men.
Successful aviation meetings were held, among other places, at Reims, Juvisy, Doncaster and Blackpool; and at Blackpool a daring flight was made in a wind of 40 m.
In 1863 the subject of aviation by vertical screws received a fresh impulse from the experiments of Gustave de Ponton d'Amecourt, G.
