Student officers in Coast Artillery School receiving instruction in balloon observation of artillery fire. The balloon is equipped with fins that act as stabilizers. The fins are automatically inflated with air by a scoop located in the lower fin or rudder. This enables the balloon to rise steadily even in high winds.
