A system for slowing an air vehicle, including an independently supported aerodynamic drag device designed so that, after contact is made between the flying air vehicle and the aerodynamic drag device, one or more parts of the aerodynamic drag device are carried along by the air vehicle thereby decelerating the air vehicle, so that a majority of a kinetic energy dissipation of a combination of the air vehicle and the aerodynamic drag device is due to an aerodynamic drag of the aerodynamic drag device.

What is claimed is: 1. A system for slowing an air vehicle, comprising an independently supported aerodynamic drag device, having a fabric sheet, and a frame system comprising: a) at least two upright support members; b) at least two elongated elements, each of said elongated elements having a direction of elongation, said elongated elements being disposed such that said directions of elongation are substantially parallel to each other, wherein said fabric sheet is slidably connected to said elongated elements substantially along a forward direction of travel of the air vehicle; and wherein said system for slowing an air vehicle is configured such that, after contact is made between the flying air vehicle and said aerodynamic drag device, at least part of said aerodynamic drag device is carried along by the air vehicle thereby decelerating the air vehicle, wherein a majority of a kinetic energy dissipation of a combination of the air vehicle and said aerodynamic drag device is due to an aerodynamic drag of said fabric sheet. 2. The system of claim 1, wherein at least 90 percent of said kinetic energy dissipation is due to said aerodynamic drag. 3. The system of claim 1, wherein said frame system and said sheet being configured such that, after contact is made between the flying air vehicle and said sheet, said sheet is at least partially draped around the air vehicle. 4. The system of claim 1, wherein at least 90 percent of said kinetic energy dissipation is due to said aerodynamic drag of said sheet. 5. The system of claim 1, wherein said frame system includes at least four elongated elements, each of said elongated elements having a direction of elongation, said elongated elements being disposed such that said directions of elongation are substantially parallel to each other, said sheet being slidably connected to said elongated elements. 6. The system of claim 1, wherein said upright support members are maintained in an upright position using guy ropes and pegs. 7. A method for slowing down an air vehicle, comprising the steps of: (a) flying the air vehicle toward an aerodynamic drag device, having a fabric sheet, at least two upright support members and at least two elongated elements, each of said elongated elements having a direction of elongation, said elongated elements being disposed such that said directions of elongation are substantially parallel to each other, wherein said fabric sheet is slidably connected to said elongated elements substantially along a forward direction of travel of the air vehicle; (b) making contact between the air vehicle and said aerodynamic drag device while the air vehicle is airborne; and (c) carrying along at least part of said aerodynamic drag device by the air vehicle thereby causing a deceleration of the air vehicle by said aerodynamic drag device, wherein a majority of a kinetic energy dissipation of a combination of the air vehicle and said aerodynamic drag device is due to an aerodynamic drag of said aerodynamic drag device. 8. The method of claim 7, wherein at least 90% of said kinetic energy dissipation is due to aerodynamic drag 9. The method of claim 7, wherein said upright support members are maintained in an upright position using guy ropes and pegs.
