O Pitts Sky Car, projetado por John W. Pitts na década de 1920, foi um dos primeiros experimentos em voo vertical. Impulsionado por um motor Curtiss OX-5 de 90 cavalos de potência, possuía um rotor circular com sessenta pás articuladas que deveriam abrir na descida para impulsionar o ar para baixo e fechar na subida para reduzir o arrasto. Embora o conceito fosse inovador, a máquina não conseguiu alcançar um voo estável. Em vez de levantar voo, quicava, pois o motor não tinha potência suficiente
