The real Re.2007 story

[archipeppe]

Actually, wing sweep was known in the aeronautical community before the war.

Yes of course, at theoretical level.
That's why it is hard to find swept wing aircraft fighter before the WWII.

I repeat, in Italy the Guidonia Research Center has conducted a lot of aerodynamical researches in several directions but none (as far as I know) in the direction of swept wings.
