1. A method comprising: impacting, by a small unmanned aerial vehicle (SUAV), a net having at least three sides; andconverting the kinetic energy of the SUAV into at least one of: elastic potential energy of one or more tensioned elastic cords connected to the net, gravitational potential energy of a frame member connected to the net, rotational kinetic energy of the frame member connected to the net, and elastic potential energy of the frame member connected to the net;wherein the frame member is a boom, wherein the boom is connected to a gooseneck connector having a vertical hinge and a horizontal hinge, and wherein the net is connected to a mast at a position distal from a portion of the mast connected to the gooseneck connector. 2. The method of claim 1 further comprising: securing the SUAV in the net after converting the kinetic energy of the SUAV by detachable entanglement of the SUAV in the net. 3. The method of claim 2 wherein securing the SUAV in the net further comprises: detachably entangling at least one barb in the net, wherein the at least one barb is disposed on a fuselage of the SUAV. 4. The method of claim 1 wherein at least one corner of the net is connected to a portion of a ship. 5. The method of claim 4 further comprising: removing, by a deck handler on the ship, the SUAV from the net. 6. The method of claim 5 wherein retrieving the SUAV from the net further comprises: rotating the boom to a location proximate to an edge of a ship. 7. The method of claim 6 wherein retrieving the SUAV from the net further comprises: lowering the mast telescopically. 8. The method of claim 5 wherein reducing the speed of the SUAV further comprises cutting power to a propeller of the SUAV. 9. The method of claim 1 further comprising: reducing, prior to impact, a closing speed of the SUAV. 10. A small unmanned aerial vehicle (SUAV) recovery system comprising: a net having at least three corners;a boom connected to at least one corner of the net;a mast, wherein the mast is oriented perpendicular to the boom;a gooseneck connector, wherein the mast is connected to the gooseneck connector by a mast connector, and wherein the boom is connected to the gooseneck connector by a boom connector;a lower clamp, wherein the lower clamp is connected to the gooseneck connector; anda stanchion, wherein the lower clamp is attached to the stanchion;wherein energy of an impact of the SUAV into the net is progressively transferred by at least one of: a vertical rotation of the boom in a direction towards the impact of the SUAV, and a horizontal rotation of the boom in a direction away from the impact of the SUAV. 11. The SUAV recovery system of claim 10 wherein energy of the impact of the SUAV is also transferred by deformation of the net. 12. The SUAV recovery system of claim 10 wherein energy of the impact of the SUAV is also transferred by a progressive bending of the boom. 13. The SUAV recovery system of claim 10 further comprising: one or more tensioned elastic cords attached to at least one corner of the net;wherein energy of the impact of the SUAV is also transferred by deformation of the one or more tensioned elastic cords. 14. The SUAV recovery system of claim 10 further comprising: three or more rings attached to the perimeter of the net; andthree or more lines, wherein each side of the net is slidably connected to one of the three or more lines by one or more of the three or more rings. 15. The SUAV recovery system of claim 10 further comprising: an upper clamp, wherein the upper clamp is disposed about an upper portion of the stanchion and a portion of the mast. 16. The SUAV recovery system of claim 10 wherein the stanchion is on a ship, and the mast, gooseneck connector, boom, and triangular net are disposed over an edge of the ship. 17. The SUAV recovery system of claim 10 wherein the mast and the boom are telescopically adjustable in length. 18. The SUAV recovery system of claim 10 wherein a square mesh size of the net is smaller than a cross-sectional size of a fuselage of the SUAV. 19. The SUAV recovery system of claim 10 further comprising: one or more barbs disposed on a fuselage of the SUAV, wherein the one or more barbs are sized to detachably entangle in the net after impact.
