1. An aircraft location system comprising: a signal location system;an aircraft structure that comprises: an acoustic reflector configured to receive, in a water environment, a sound signal, from the signal location system, and reflect, into the water environment, an echo of the sound signal;a signal generator associated with the aircraft structure;a detector configured to receive the echo, and associated with a controller, the controller connected to the signal generator, and configured such that in operation, in response to receipt of the echo, the controller activates the signal generator; andthe signal generator being connected to a light and configured such that in operation the light generates light signals in response to being activated by the controller after the detector receives the echo. 2. The aircraft location system of claim 1, wherein the sound signal comprises a frequency in a range selected for locating the aircraft structure. 3. The aircraft location system of claim 2 further comprising a second signal generator, wherein the second signal generator comprises an additional acoustic reflector, the second signal generator configured such that in operation, in response to being activated by the acoustic reflector, the second signal generator generates signals for locating the aircraft structure. 4. The aircraft location system of claim 3, further comprising: the acoustic reflector configured to generate a number of first echoes that comprise a first frequency; andthe additional acoustic reflector configured to generate a number of second echoes that comprise a second frequency that differs from the first frequency. 5. The aircraft location system of claim 2 further comprising: a number of acoustic reflectors associated with the aircraft structure, wherein the number of acoustic reflectors is configured to generate a number of echoes in response to receiving the sound signal. 6. The aircraft location system of claim 2 further comprising a power source configured to power the signal generator. 7. The aircraft location system of claim 2, wherein the light signal comprises a light beacon. 8. The aircraft location system of claim 1, wherein the aircraft structure comprises a cavity in which a light signal generator in the signal generator is located, the cavity configured such that the light signal generator operates after an unintended encounter of the aircraft with the water environment, wherein the aircraft structure is associated with the aircraft. 9. The aircraft location system of claim 8, wherein the aircraft structure has a number of channels connecting an exterior of the aircraft structure to the cavity. 10. The aircraft location system of claim 8 further comprising: a channel connecting an exterior of the aircraft structure to the cavity; anda moveable structure configured to open up the channel, wherein water moves through the channel into the cavity when the aircraft structure is underwater. 11. The aircraft location system of claim 10, wherein the moveable structure is configured to open up the channel when the aircraft structure is at least partially underwater. 12. The aircraft location system of claim 8 further comprising: a tether having a first end connected to the aircraft structure and a second end connected to the light signal generator in the signal generator. 13. An aircraft location system that comprises: a signal location system;a first aircraft structure that comprises a first signal system and one of: a fuselage, and a tail section, such that the first signal system comprises: a first detector;a first acoustic reflector configured to receive, in a water environment, sound signals from the signal location system, and reflect, to the first detector, in the water environment, first echoes of the sound signals;a first controller connected to and configured to activate, for a period of time less than a life of a battery of a first number of signal generators associated with the first aircraft structure, and based upon receipt of the first echoes by the first detector, the first number of signal generators; anda second aircraft structure comprising a wing, and a second signal system that comprises: a second detector;a second acoustic reflector configured to receive, in the water environment, the sound signals from the signal location system, and reflect, second to the second detector, in the water environment, second echoes of the sound signals; anda second controller connected to and configured to activate, for a period of time less than a life of a battery of a second number of signal generators associated with the second aircraft structure, and based upon receipt of the second echoes by the second detector the second number of signal generators. 14. The aircraft location system according to claim 13 further comprising: a third aircraft structure comprising an engine housing and a third acoustic reflector; anda third number of signal generators associated with the third aircraft structure, the third number of signal generators configured to generate signals in response to the third acoustic reflector receiving, in the water environment, the sound signals from the signal location system. 15. The aircraft location system according to claim 13, wherein the first number of signal generators and the second number of signal generators comprise at least one of: active, and passive, signal generators. 16. The aircraft location system according to claim 15, wherein the active signal generators comprise radio frequency signal generators and the passive signal generators comprise acoustic reflectors. 17. The aircraft location system according to claim 15, wherein the active signal generators comprise light signal generators. 18. The aircraft location system of claim 1, further comprising a survivability system for the acoustic reflector, the survivability system configured to protect the acoustic reflector from a force up to 40 times a force of gravity. 19. The aircraft location system of claim 13, further comprising a survivability system for each acoustic reflector, such that survivability system is configured to protect each acoustic reflector from a force up to 40 times a force of gravity.
