At Skydive Hastings students start with a tandem skydive. A USPA-certified instructor jumps with them, guiding them through the freefall and parachute deployment. Once they've completed the appropriate amount of jumps, students can graduate to WMSA's more extreme air sports, such as freeflying, in which jumpers move through a series of positions during their freefall, including back-to-Earth, head-up flying, and head-down flying. There's also wingsuit flying, for which jumpers sport a suit equipped with extra fabric between the legs and under the arms. The suit, which is colloquially referred to as a flying squirrel or bat suit due to its resemblance to those animals, allows jumpers to quite literally fly through the air, whether from a plane jump or BASE jump point.
