What is the summary of the short story flying by margo mcloughlin?

There are two kinds of people in this story, the ones who have the ability to fly and those who do not - the Groundwalkers. Since "Collection Day", when all the flyers were rounded up, it is now a crime to fly. Jessie must demonstrate how well the re-education succeeded, but will she be able to convince herself that she is happy to be grounded?
