Wings of Valor : Air Crew Member

Once the plane got back to base, it was up to the ground crew to check for damage, and to repair the aircraft for another flight.  The wings are shown.

The image is that of the seal of the United States.  There is a circular figure placed above the head of the eagle.  It appears to be a sun burst surrounded by a circle of starts.  Does anyone know its symbolic meaning?

Keep'um flying.
