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

one of said tethers, are capable to take-up some of the tether to reduce the length
of said tether.
