The Kennedy Giant was a British biplane heavy bomber designed by Kennedy Aeroplanes Ltd. during the First World War. The design was an imitation of works by Igor Sikorsky, with whom the owner of Kennedy Aeroplanes Ltd., C. J. H. Mackenzie-Kennedy, had ostensibly worked prior to setting up the company. The aeroplane was a notorious failure; its size meant that construction had to take place in an open field as none of the hangars near Hayes, Middlesex, where the prototype was assembled, were large enough to house it. For its weight, the aircraft's four engines were inadequate, and the resulting under-powered aircraft could only fly in a straight line once airborne.
