Ever since its debut in the late 90s, the Harry Potter series of books written by J.K. Rowling have become immensely popular, and young readers of the books often hoped and prayed for their own acceptance letters to Hogwarts. People will wear Hogwarts costumes, and have created simulations of various drinks and treats mentioned in the books.
One of the most oddly popular adaptation was the fictional sport of Quidditch which involved flying brooms. Amateur Quidditch teams and leagues have popped up around the world, with people playing the sport on the ground. That was unacceptable to these skydiving Harry Potter aficionados who decided to take the sport to the next – and weirdly more logical – level.
