and so this is actually a fundamental question being looked at by the naca in langley, virginia. fred weick who has a 20 foot wind tunnel that he starts playing with the idea of a cowling for a radial engine. it's design number ten that results in flowing air through the cowling to cool the engine whilst controlling the streamline of the air on the outside. and so that technology is what makes the vega such an important aircraft in terms of its efficiency and it maximizes its ability to fly 165 miles per hour cruise and the ability to fly passengers in what the original design of the airplane was for. and so the naca cowling which wins the highest award for achievement in aviation is still given today. jack northrup, takes it, puts it on this airplane. he also thinks about this is a high reliever airplane. where would you put the landing gear on this? so you have fixed landing gear from the bottom of the aircraft. and you have these big rubber tires and wheels that create drag. and so his ideas, well, i'll put pants on the tires and the wheels. so there's tear dropped streamline
