It seems more and more common to use drones and quadcopters during sporting events. In the 2017 Portuguese Cup football final (before the Benfica vs Vitoria Guimares matech), a mysterious man delivers the match ball to the referee on a spider-like drone.
Netizens commented that this unusual scene resembles to the Marvel supervillian the Green Goblin riding through the air with the iconic glider.
In the video above, the man is actually riding a propeller-powered Omni hoverboard, which can only stay in the air for a short few minutes.
Other than man on a drone, in the NBA Slam Dunk Contest, an Intel Drone assisted Aaron Gordon in the contest.
