iFly indoor sky diving is exactly what the title says instead of jumping from a plane you can get almost the same feeling from indoors. You watch a quick video explaining how things work and what hand signals mean what so you can communicate whilst in the wind tunnel. if your an adrenaline junkie this is for you. For an extra $10 you can choose to do the high fly, this is where an instructor guides you up to the highest part of the tunnel.
