Answer:
It means that she literally ran away from the supervisor, flying like a bird.
Explanation:
This question is about "The People Could Fly," which tells the story where a portion of African slaves taken by force to America managed to use their own bodies to fly. This made it possible for these slaves to escape the terrors of slavery, flying over fences and overgrowers who tried unsuccessfully to arrest them. In this case, the phrase "She flew like an eagle" means that the girl flew, like a bird, using her own body.
