Blackburn AD Scout
Harris Booth of the Admiralty (or A.D.) designed this anti-airship fighter for naval use. Although of conventional wood and fabric construction, the fuselage nacelle was attached to the top wing rather than the bottom. This gave the pilot/gunner an excellent all-round view but contributed nothing to stability.
The Scout (unofficially called the Sparrow) was intended to carry a Davis two-pounder recoilless gun, but the structure wasn't up to such a weapon. An ordinary Lewis gun was fitted instead. The ability of a single man to fly the aircraft, load, fire and reload these heavy guns was always doubtful. RNAS pilots found the Scout was overweight with extremely poor handling. The Admiralty accepted it, but got rid of it as unsatisfactory within a month.
