The Supermarine Spiteful was a British Rolls-Royce Griffon-engined fighter aircraft designed by Supermarine to Air Ministry specification F.1/43 during the Second World War as a successor to the Spitfire. It had a new wing design, to improve its critical Mach number and allow safe operations at higher speeds. The new design also had a modern inwards-retracting undercarriage. Other changes included a larger fin to improve the somewhat marginal stability of Griffon Spitfires and changes to the mounting of the engine to tilt it down slightly for better visibility over the nose.

The Fike Model D was a light aircraft built in the United States in the early 1950s. Designed by airline pilot William Fike, it was a conventional high-wing strut-braced monoplane with tailskid undercarriage and seating for one or two people in an enclosed cabin. In appearance, the aircraft strongly resembled a Piper Cub, with only the tail surfaces sourced from one. An unusual feature was that the flight controls were mounted to the ceiling of the cabin, rather than the floor. This facilitated the folding or removal of the seat or seats to enable the aircraft's use as a sleeping space when camping with it. Plans were marketed for homebuilding.
