A balloon with the aerodynamic shape of a kite, preferably for use in an emergency rescue kit, for those stranded in a boat at sea, or injured or lost in the wilderness. The present invention consists of a balloon specifically shaped with an aerodynamic configuration with a leading edge and a trailing edge like an airplane wing, with a main body portion and a complementary cylindrical portion. This balloon is made of a radar reflective material with a high degree of resistance to puncture and deflation, preferably a biaxially oriented 48 gauge nylon laminated with a low density 70 gauge polyethylene, then sprayed with melted aluminum. A valve, preferably a bladder valve, allows passage of gas in only one direction, into the body portion from the cylindrical portion. The invention is secured to the ground by a tether, preferably a string composed of a combination of nylon and silk. This string is attached to the balloon, preferably by glue with a high degree of resistance to outdoor environments, such as a hi-tack acrylic adhesive. It is affixed to a ring shaped element to which are also affixed a plurality of holding strings made of the same material as the tether string, such holding strings being affixed to a plurality of points on the circumference of the balloon in order to spread the stresses caused by wind on the balloon. The balloon is preferably part of an emergency rescue kit which includes the kite balloon, a small cylinder containing helium to inflate the balloon by means of a manifold, and a portable container to hold the emergency kit. A retaining clip may be attached to the spout of the manifold in order to secure the kite balloon while it is being inflated.
