‘One Hot Yankee’ describes the first plane off the American Aviation production line. It was hot because:
It flew Hot like a fighter, fast and responsive
It was Hot Looking with very sexy lines
It was Hot because you had almost no airflow on your ankles cause there were no NACA scoops in the sides of the fuselage and the solar heating through the canopy was fierce. So most flew canopy open a few inches even in winter.
