Shield
Teal blue and white were the colors formerly associated with Aviation organizations. The wings symbolize flight operations. The annulet is used to allude to an eyelet, an item for securing, and a place for observing. The saltire cross stands for the state of Indiana, which is called The Crossroads of America. An X has long been used to mark a definite location; in this connection the saltire also refers to the units reconnaissance activities.
