Terence O'Neill's Pea Pod N10T of 1963 was a diminutive machine in which the pilot lay in a prone position, with most of his body inside the wing. It was powered by a 35 hp Kiekhaefer O-4-35 boat engine mounted inside the vertical fin, and could be carried atop the family car. Taxi tests were performed, but it could not meet FAR 103 requirements and reportedly never flew.
