Skydiving is a crazy sport. You jump out of a plane thousands of feet up in the sky, fall at over 100 miles an hour, then pull your parachute to slow you down to land. But if LOTS of skydivers jump at once, they can grab each other's arms to make pictures in the sky. In this video, we see how 164 divers steered to fall faster or slower to meet each other in the sky. Some dove 175 miles an hour! Their awesome star shape broke the record of 100 group divers -- and everyone's parachute worked!
