A tethering system for controlling an inflatable airfoil is provided. The inflatable airfoil has a horizontal center line and a vertical center line. The tethering system includes an airfoil wing secured to the inflatable airfoil. A first forward attachment ring is secured to the inflatable airfoil. A second forward attachment ring is secured to the inflatable airfoil. A rear attachment ring is secured to the inflatable airfoil. A center attachment ring is secured to the inflatable airfoil. A first airfoil reinforcement strap is secured between the first forward attachment ring and the center attachment ring. A second airfoil reinforcement strap extends between the second forward attachment ring and the center attachment ring. A third airfoil reinforcement strap extends between the rear attachment ring and the center attachment ring. A control mechanism controls the inflatable airfoil during flight.
