sergeant barth begins lowering deputy paramedic mark demarto toward the woman. both men are wearing helmet cameras. >> as soon as i left the bird, i started to spin due to the rotor wash. i needed to stop this spin as fast as i can and get it stopped in a safe manner away from our victim. >> he doesn't want to accidentally bump into the woman and knock her off the rock face. >> i was able to point out a spot on the cliff where i could safely stop my spinning. basically, it's a flintstone maneuver. you stick your foot out against the cliff face and you come to a stop. okay. good. then get to the task at hand and complete the rescue. >> but demarto is still getting pushed away from the rock by the wind kicked up by the helicopter's powerful rotor. he uses hand signals to communicate with barth.
