Just like Carter said, what they did every day was patrol in planes or bomb enemy balloons. The latter was like releasing fireworks in the sky: press the fire button and then wait for the bright fireballs to bloom in the air.
As for patrolling, it was even more enjoyable. They had complete control of the air. The enemy planes, upon seeing them from afar, would flee like chicks evading an eagle.
Shire said calmly, "One day, Lieutenant, one day you will have to face enemy machine-gun planes."
Carter was shocked: "Do you know something? Have the Germans discovered the secret of the 'machine-gun synchronizer'?"
"No, Carter!" Shire shook his head. Instead of answering, he asked a question: "Have our planes had accidents recently?"
"Of course!" Carter nodded: "During missions, there have been a total of seventeen major accidents, with eleven pilots injured or killed. This is unavoidable in flying..."
Before he finished speaking, Carter understood what Shire meant.
