Poised briefly on the edge, jump-suit-clad guests gaze down at Northern California's rolling landscape as it sprawls out thousands of feet below. The whir of the 950-horsepower Cessna Grand Caravan drowns out the sound of a deep breath before a small jump transforms the mechanical din into a constant, enveloping whoosh as adventurers rush toward the ground in free fall. Established in 1987, Skydance Skydiving has engineered such peerless adrenaline rushes for thousands of thrill seekers, ensuring safety through training and expertise. Tandem jumps keep newbies in the able hands of attached professionals, who deploy the ’chutes and prevent their charges from realizing that all humans possess the power of flight. Prospective solo jumpers can enroll in classes that gradually work up to an unassisted jump, following thorough classroom training and assisted jumps.
