A system and methods for airborne launch and recovery of aircraft. In one embodiment the system comprises a flexible tether configured to be towed behind an airborne mother ship. A drag device is secured to a distal end of the flexible tether to generate drag and maintain tension in the flexible tether. A reel associated with the mother ship anchors a proximal portion of the flexible tether and selectively lets out and takes up the flexible tether to adjust a length of the flexible tether. A capture mechanism associated with the aircraft engages the flexible tether to secure the aircraft to the flexible tether. In certain embodiments of the present methods, a flexible tether is deployed from an airborne mother ship. An aircraft translates forward and rearward along the flexible tether. Alternatively, the aircraft translates forward and rearward as the flexible tether taken up and let out from the mother ship. Prior to launch, the weight of the aircraft is transferred from the flexible tether to the wings. During recovery, the weight of the aircraft is transferred from the wings to the flexible tether.

1. A system for airborne launch and recovery of an aircraft, comprising: an airborne mother ship;a flexible tether attached to the airborne mother ship and configured to be towed behind the airborne mother ship;a drag device secured to a distal end of the flexible tether, the drag device being configured to generate drag and maintain tension in the flexible tether;a reel attached to the airborne mother ship, the reel being configured to anchor a proximal portion of the flexible tether and to selectively let out and take up the flexible tether; anda capture mechanism connected to the aircraft, the capture mechanism being configured to engage the flexible tether to secure the aircraft to the flexible tether. 2. The system of claim 1, wherein the capture mechanism fixes a position of the aircraft along the flexible tether. 3. The system of claim 1, wherein the drag device includes apparatus that enables a magnitude of the drag generated by the device to be adjusted. 4. The system of claim 1, further comprising a sensor configured to detect a position of the flexible tether. 5. The system of claim 1, wherein the drag device comprises a ballute. 6. A method for airborne launch of an aircraft, the method comprising the steps of: deploying a flexible tether from an airborne mother ship;translating an aircraft, including wings, rearward away from the mother ship; andtransferring the weight of the aircraft from the flexible tether to the wings. 7. The method of claim 6, wherein the step of translating the aircraft rearward away from the mother ship comprises letting out additional length of the flexible tether from the mother ship as a position of the aircraft upon the flexible tether remains fixed. 8. The method of claim 6, further comprising the steps of aborting the launch and recovering the aircraft. 9. The method of claim 6, further comprising the step of releasing the aircraft from the flexible tether. 10. The method of claim 6, wherein the step of deploying the flexible tether includes deploying a drag device secured to a distal end of the flexible tether. 11. The method of claim 6, further comprising the step of securing the aircraft to the flexible tether. 12. The method of claim 6, further comprising the step of arresting further translation of the aircraft prior to the step of releasing the aircraft from the flexible tether. 13. The method of claim 6, wherein the step of transferring the weight of the aircraft from the flexible tether to the wings comprises at least one of deploying the wings, unfolding the wings, collapsing spoilers on the wings, and morphing the wings. 14. The method of claim 6, further comprising the step of supporting the aircraft on a cradle. 15. A method for airborne recovery of an aircraft, the aircraft including wings, the method comprising the steps of: deploying a flexible tether from an airborne mother ship;the aircraft engaging the flexible tether;transferring the weight of the aircraft from the wings to the flexible tether; andtranslating the aircraft forward toward the mother ship. 16. The method of claim 15, wherein the step of translating the aircraft forward toward the mother ship comprises taking up length of the flexible tether into the mother ship as a position of the aircraft upon the flexible tether remains fixed. 17. The method of claim 15, wherein the step of deploying the flexible tether includes deploying a drag device secured to a distal end of the flexible tether. 18. The method of claim 15, further comprising the step of performing at least one of refueling the aircraft, rearming the aircraft and servicing the aircraft. 19. The method of claim 15, further comprising the step of re-launching the aircraft. 20. The method of claim 15, further comprising the step of locating the flexible tether. 21. The method of claim 20, wherein the step of locating the flexible tether comprises an optical sensor, light detection and ranging (LIDAR), or a differential global positioning system (GPS). 22. The method of claim 15, wherein the step of transferring the weight of the aircraft from the wings to the flexible tether comprises at least one of stowing the wings, folding the wings, spoiling the wings, and morphing the wings. 23. The method of claim 15, further comprising the step of supporting the aircraft on a cradle.
