An air drop device that includes a frame defining a through-hole and that supports a substantially vertical axle, substantially central to the through-hole. A blade assembly is rotatably mounted to the substantially vertical axle. Also, at least three tethers are connected to the frame and are adapted to be connected to the load. In addition, a set of tether length adjust devices, each located on a different one of said tethers, are capable to take-up some of the tether to reduce the length of said tether.
