The Brazilian Helicopter Pilot is a character from Inside Out. It is presumed that Riley's mother knew him at some point before marrying Riley's father, and that he had proposed her to stay with him. His memory holds a special place in the mother's mind. When disappointed by her husband, her Anger emotion is shown to mention the pilot frequently, bringing up his memory orb which shows him asking Riley's mother to "come fly with me."
During the end credits, it is revealed Riley's teacher has the exact same memory. For her, it represents her dreams of summer vacation when disappointed by her students.
