Hiker Jason Koch was trying to rescue his fallen drone when he wound up needing rescuing himself. Koch was climbing across big rocks in the Northern California town of Calistoga, searching for his downed aircraft when he lost his balance and slipped, ending up pinned under a massive boulder. With his cellphone dying in his pocket, and temperatures starting to drop, Koch knew he had to figure a way out. Finally he was able to free himself after nine hours.
