A flight configuration is disclosed. The flight configuration includes a lift configuration in which a lift aircraft lifts a powered payload via a tether. The flight configuration comprises a series of steps for transitioning from the lift configuration to a forward flight configuration. In the forward flight configuration, the lift aircraft and the powered payload are in horizontal alignment.

1. A system to lift and transport a payload comprising: two or more lift aircraft configured to lift the payload via respective tethers in a lift configuration in which each lift aircraft is tethered to the payload but not coupled rigidly to any other ones of the two or more lift aircraft, the two or more lift aircraft fly independently on a shared elliptical trajectory, and at least one of the two or more lift aircraft maneuvers independently of the other lift aircraft to maintain a position on the shared elliptical trajectory relative to one or more other of the lift aircraft; anda processor configured to: receive an indication to transition to a forward flight configuration in which the lift aircraft and the payload fly together in a forward flight direction; andcompute and initiate a series of maneuvers to transition the one of more lift aircraft and the payload from the lift configuration to the forward flight configuration in which the lift aircraft fly substantially in parallel in the forward flight direction. 2. The system of claim 1, wherein a flight configuration instruction is provided to the payload and the lift aircraft. 3. The system of claim 1, wherein the payload or the lift aircraft comprises an interface and the processor. 4. The system of claim 1, wherein the forward flight configuration comprises the payload towing the lift aircraft behind the payload. 5. The system of claim 1, wherein the forward flight configuration comprises the lift aircraft towing the payload behind the lift aircraft. 6. The system of claim 1, wherein the series of maneuvers comprises increasing or decreasing power to the payload or the lift aircraft. 7. The system of claim 1, wherein the payload is powered. 8. The system of claim 1, wherein the payload provides power to the lift aircraft and the tether is powered. 9. The system of claim 1, wherein the payload and the lift aircraft each receive telemetry information about the other. 10. The system of claim 1, wherein a propeller of the lift aircraft is recharged in the forward flight configuration. 11. The system of claim 1, wherein the payload is optimized for cruising. 12. The system of claim 1, wherein one or more additional lift aircrafts are tethered to the payload. 13. The system of claim 1, wherein the flight configuration comprises the payload towing the lift aircraft and a second lift aircraft behind the payload, wherein the angle between the first lift aircraft and the second lift aircraft is determined to minimize tether drag. 14. The system of claim 1, wherein the flight configuration comprises the lift aircraft and a second lift aircraft towing the payload behind the lift aircraft and the second lift aircraft, wherein the angle between the first lift aircraft and the second lift aircraft is determined to minimize tether drag. 15. The system of claim 1, wherein the lift configuration comprises the lift aircraft and a second lift aircraft flying in a periodic trajectory. 16. The system of claim 1, wherein the lift configuration comprises the lift aircraft and a second lift aircraft flying in a periodic trajectory with a fixed phase difference between the lift aircraft and the second lift aircraft. 17. The system of claim 1, wherein the forward flight configuration comprises a change in a phase difference between the lift aircraft and a second lift aircraft. 18. The system of claim 1, wherein the forward flight configuration comprises the lift aircraft and a second lift aircraft flying in parallel. 19. A method to lift and transport a payload, comprising: receiving an indication to transition from a lift configuration, in which two or more lift aircraft are configured to lift the payload via respective tethers, to a forward flight configuration, in which the lift aircraft and the payload fly together in a forward flight direction; andcomputing and initiating a series of maneuvers to transition the one of more lift aircraft and the payload from the lift configuration to the forward flight configuration;wherein in the lift configuration each lift aircraft is tethered to the payload but not coupled rigidly to any other ones of the two or more lift aircraft, the two or more lift aircraft fly independently on a shared elliptical trajectory, and at least one of the two or more lift aircraft maneuvers independently of the other lift aircraft to maintain a position on the shared elliptical trajectory relative to one or more other of the lift aircraft, and in the forward flight configuration the lift aircraft fly substantially in parallel in the forward flight direction. 20. A computer program product for a flight configuration for a payload and a lift aircraft, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for: receiving an indication to transition from a lift configuration, in which two or more lift aircraft are configured to lift the payload via respective tethers, to a forward flight configuration, in which the lift aircraft and the payload fly together in a forward flight direction; andcomputing and initiating a series of maneuvers to transition the one of more lift aircraft and the payload from the lift configuration to the forward flight configuration;wherein in the lift configuration each lift aircraft is tethered to the payload but not coupled rigidly to any other ones of the two or more lift aircraft, the two or more lift aircraft fly independently on a shared elliptical trajectory, and at least one of the two or more lift aircraft maneuvers independently of the other lift aircraft to maintain a position on the shared elliptical trajectory relative to one or more other of the lift aircraft, and in the forward flight configuration the lift aircraft fly substantially in parallel in the forward flight direction.
