Shocking video shows the moment that a Dallas man loses his grip and flies off the edge of a water slide. David Salmon was gliding into a curve when his momentum launched him over the lip of the slide. Salmon fell 10 or 15 feet to the ground below, according to Fox-4. “Too dang old to be going down water slides,” Salmon said in a Facebook post. “Fell off this one that is over a rocky cliff.” The slide is located at a private residence, according to the Fox station. Rescue crews had a difficult time reaching Salmon because of the terrain around the slide. He was eventually brought to a hospital in Round Rock, Texas.
