It looks like the DC-3 (and probably the DC-1 &2 ) had a considerable wing sweep.... more then any other propeller driven aircraft I would say.... and almost as much as the ME 262 jet fighter. I am curious about this design feature   Herman |

I’ve noticed that too and I assumed it was done to put the center of the wing at what ended up being the CG.

Checked with google and found this statement: "The wing was swept to move the center of lift back, closer to the center of gravity. When the design of the DC-1 was advanced to a point where the center of gravity became clear, a redesign of the wing-fuselage intersection would had been more effort, so the outer wing panels were swept back a little."
This included the DC-1, DC-2 and DC-3.
Kinda reminds me of the Lear 45 I used to fly in another life...trailing edge was perpendicular to the fuselage while the leading edge was swept back.

Herman's pic of NC17334 over New Mexico is absolutely gorgeous!
My very first ride in an airplane was a Mohawk Airlines DC-3 from Buffalo to Binghamton, N.Y. in 1958.
Boy, did I get airsick!

Thank you Tom and Phil for your explanations. An interesting reason having to do with a form of aerodynamics. I never would have known that. I had always assumed that it might be linked to the possibility in the wing sweep allowing for a higher cruising speed. Aesthetically an aircraft with a swept wing makes it look faster.  Yes Phil this flight was from El Paso to Tucson NM.  Herman |
