1. A system comprising a plurality of airborne platforms, each airborne platform comprising an unmanned balloon;

  • a payload that is separate from the unmanned balloon;

    a transceiver;

    a flight termination device;

    at least two separate power sources for the flight termination device;

    a sensor;

    a processor;

    a pump; and

    a valve;

    wherein the pump and the valve are configured to change an altitude of the airborne platform;

    wherein the sensor comprises a pressure sensor;

    wherein, in operation, the unmanned balloon substantially drifts along with the wind currents;

    wherein the transceiver is capable of communicating with a communication device that is separate from the unmanned balloon;

    wherein the flight termination device has an ability to terminate a flight of the unmanned balloon;

    wherein at least one of the geographical coordinates tracking system comprises a GPS;

    wherein the unmanned balloon is configured to operate above an attitude of about 60,000 feet;
