On the other hand, the single-seater tractors were potentially the superior fighters, and in order to protect the blades of the airscrew the French were the first to use deflector blades on them in tractor machines.
Our early single-seater tractors were fitted with a Lewis gun fixed so as to fire over or at the side of the airscrew and actuated by a bowden wire, the most efficient, though not the most numerous, fighting machines at the end of 1915 being the Bristol Scouts.
The machine gun soon followed, but its use in tractor machines was impracticable on account of the danger of hitting the airscrew.
The monoplane, from the first, was a 'tractor' machine; its airscrew was in front of the planes, and its body, or fuselage, was covered in and streamlined, so as to offer the least possible resistance to the air.
