Junkers JU-2
The JU-2 was Germany's answer to the DC-3. This Lufthansa example is immaculately restored.A few are still flying today at air shows.
I know that corrigation makes metal stronger to deflection in one direction, I am baffled at how the air tollerates this and lets these planes fly (okay.. at low speeds).
The extra drag may add to lift like a stealth fighter flying on vortexes of swirlie air?
