Another weird one is on the Avro Arrow. Looks like the wing is on upside down. That's them Canucks for you.

Top of the wing is flat. All of the curve on the bottom. When you stop and think of it, makes sense. Have an EDF in the works to try it out.
It's not just our Arrow. The Delta Dagger and Dart used the same airfoil.... or at least ONE of them did. I think you'll find the same airfoil in a few of the delta or other extreme chord full sized airplanes as well.
Even airliners use these sorts. Looking through Profili shows you a few ailiner root airfoils that look like they are mostly upside down. Sort of spits in the eye of the Bernulli principle.
