"THE GREAT GAZOO"
It surprises me how so many transports prior to the DC3 were so obviously unaerodynamic. Transports are slow in aviation terms but 150-200MPH is fast for a car and you never see high performance cars looking like a house brick.
Sometimes the thought process is that a transport is just a "pick up truck." Why make it fast or aerodynamic when all it had to do is haul stuff?
