Hi Brian, I take your point, unless the shape of the wing is modified to allow for the loss of camber?
I was just trying to give a simple and backed up, (Davis), reference that might be suitable for an interview.
I went to an airshow at Thorny Island way, way back and when a Swift flew over I asked, "Why the swept back wing?" and the answer from an RAF chap nearby was, "So that it can go faster".
