Step-by-step explanation:

This line reveals Twain's inexperience and the nervousness of being a young pilot under great pressure.
It is evident that he wishes to perform well and is concerned about the absence of instructions, making him feel out of control and desperate to explain the situation to his superior.
The mention of the apology suggests that Twain is also respectful and possibly timid in this scenario, not wanting to appear incompetent or disobedient.
