1. A launching system for an unmanned aerial vehicle, comprising: (a) a launcher rail;(b) a shuttle configured to travel along the launcher rail;(c) a drive mechanism for moving the shuttle along the launcher rail, the drive mechanism comprising (i) a motor-driven tape running along the launcher rail, the motor-driven tape having an interface that is detachably securable to an undercarriage of the shuttle, (ii) an electric drive motor that drives movement of the tape, and (iii) a power reel to which one end of the tape is secured and around which the tape is wound during launch, wherein the shuttle releases from the motor-driven tape during launch. 2. The launching system of claim 1, wherein the tape is wound onto the power reel during launch to accelerate the shuttle. 3. The launching system of claim 1, further comprising a payout reel having another end of the tape secured thereto. 4. The launching system of claim 3, wherein the payout reel is used to rewind the tape following a launch sequence and re-position the shuttle into a launch ready position. 5. The launching system of claim 3, wherein the payout reel is motorized or manually rotated for rewind operations. 6. The launching system of claim 1, wherein the payout reel is positioned on a base plate below the launcher rail. 7. The launching system of claim 1, wherein the shuttle separates from the tape during launch. 8. The launching system of claim 1, wherein the shuttle to tape interface comprises a hook on the undercarriage of the shuttle and a corresponding protrusion on the tape. 9. The launching system of claim 1, wherein the shuttle to tape interface comprises a connection on the undercarriage of the shuttle and a corresponding connection feature on the tape. 10. The launching system of claim 1, wherein the shuttle to tape interface comprises a connection on the shuttle that secures two ends of the tape to one another, such that the tape may be discontinuous. 11. The launching system of claim 1, wherein the electric drive motor is stationary with respect to the launcher rail in use. 12. The launching system of claim 1, further comprising first and second sheaves positioned at first and second ends of the launcher rail, wherein the tape is directed over the first and second sheaves. 13. The launching system of claim 1, wherein the tape is comprised of a material that offers a degree of cushioning during initial application of launch load. 14. The launching system of claim 1, wherein the tape comprises nylon or a nylon blend. 15. The launching system of claim 1, wherein the electric motor is a DC motor. 16. The launching system of claim 1, wherein the electric motor is powered by one or more batteries or capacitors. 17. The launching system of claim 16, wherein the battery comprises a lithium ion battery. 18. The launching system of claim 1, wherein the electric drive motor and the power reel are positioned on a base plate below the launcher rail. 19. The launching system of claim 1, wherein the tape comprises a first component of launch tape secured to a forward portion of the shuttle and a second component of arresting tape secured to a rear portion of the shuttle. 20. The launching system of claim 1, wherein the launcher rail is an inclined ramp. 21. A launching system for an unmanned aerial vehicle, comprising: (a) a launcher rail;(b) a motor-driven tape configured to travel a length of the launcher rail;(c) a shuttle secured to the tape at a shuttle to tape interface;(d) a power reel driven by an electric drive motor that drives movement of the tape; and(e) a payout reel, wherein the shuttle releases from the motor-driven tape during launch. 22. The launching system of claim 21, wherein the payout reel allows the tape to peel off in a controlled manner during the launch sequence. 23. The launching system of claim 21, wherein the payout reel is used to rewind the tape following a launch and move the shuttle into a launch ready position, decreasing the time to reset the system for subsequent launch cycles. 24. A launching system for an unmanned aerial vehicle, comprising: (a) a launcher rail;(b) a shuttle configured to travel along the launcher rail;(c) a drive mechanism for moving the shuttle along the launcher rail, the drive mechanism comprising (i) a motor-driven belt running along the launcher rail, the belt having an interface secured to the shuttle; (ii) an electric drive motor that drives movement of the belt, and (iii) a conveyor that moves the belt in a loop, wherein the shuttle releases from the motor-driven belt during launch. 25. The launching system of claim 24, wherein the loop comprises a continuous loop. 26. The launching system of claim 24, wherein the loop comprises a discontinuous loop. 27. The launching system of claim 1, wherein the motor-driven tape is comprised of a material that has more elasticity or stretch than a steel cable. 28. The launching system of claim 1, wherein the motor-driven tape is a flat tape.
