Air Force aviation badges are commonly called "wings." They indicate the flying position and type of rating you hold.
I'll try to add more of these when I can, and give some history behind the various wings there are.
This first pair is from my dad. He flew as a crew chief during WW II.

These are the wings I wore as an aircrew member on the Looking Glass.
