MARCH 27, 1909. " night " Copyright J'hoto. AERO SHOW AT OLYMPIA..—Captain Windham's Pischoff flyer seen from in front. One of the rightingplanes, which are mounted midway up the outside stays, is clearly visible. The rudder, which should be between the planes of the rear tail, is not shown. operate the movements of a pair of small righting planes which are pivoted midway between the main planes at each extremity. The elevator and rudder, the latter being in the middle of the tail, are controlled by a single lever operated by the driver's right hand. The engine with which the machine is at present equipped is a 2-cyl. Dutheil-Chalmers, but the machines which Captain Windham will construct in this country will have 4-cyl. engines of the same make. Breguet (J-STENBURY). :•' The Breguet biplane, exhibited by the concessionaire, Mr. J. Stenbury, is a very different machine to the combined helicopter-biplane which the same designer exhibited in Paris, but it nevertheless embodies equally uncommon ideas. As a system it is peculiar, not to say unique, amongst biplanes, in having absolutely no sort of supplementary surface in front of the main planes, which are themselves so mounted that they can tilt for elevating and righting purposes. The details of the control levers and wires are not fitted, and, indeed, the machine is far from complete. A compiratively short distance behind the main planes are a set of large tail planes, these being arranged in biplane form, but with the upper deck three times the spread of the lower deck. Between the two decks are a pair of vertical rudders. The whole structure has a most massive appearance, owing to the fact that it is built up entirely of steel tubes, some of which are no less than 2^ ins. in diameter. The tubular spars, which support the main surfaces, are jointed to the main frame- work, so that the planes can be folded back out of the way for transport; when extended the joint is locked solid by using the spar itself as an internal bolt. In consequence of the large diameter of these tubular spars which pass through between the double surfaces of the planes, the planes themselves are of unusual thickness. " flight Copyright Photo. AERO SHOW AT OLYMPIA.— The Breguet Biplane, seen from behind* Tubular steel of large diameter is used throughout in its construction, and knuckle-joints are introduced to enable the planes to fold back out of the way. The forward planes are pivoted for elevating. The machine is unfinished. 177
