Young pilot
It means a young man fall in love with an older woman. Old woman is often referred to "old lady plane". Therefore, to "control" the "old lady plane", the "young pilot" must be in charge of it. We can abbreviate the meaning by saying someone wants to drive an old lady.
Although she looks old, I want to drive her because her body is so perfect.
Do not become a young pilot, she looks ugly.
