1. A miniature, unmanned aircraft for handling data, comprising:

  • an airframe including a fuselage, a wing fixed to said fuselage, a reciprocating piston internal combustion engine supported on said aircraft, a propeller drivably connected to said engine, control surfaces operably attached to said aircraft and electrical power consuming devices carried aboard said aircraft including a servomechanism operably connected to each said control surface, a microprocessor carried aboard said aircraft, for managing flight control, a radio frequency receiver connected to said microprocessor, and a data handling apparatus disposed to receive data;

    a data handling module including a housing which is manually removably attached to said aircraft and which is disposed to substantially enclose said data handling apparatus, and manual fasteners for removably attaching said housing to one of said fuselage and said wing;

    an electrical power supply system disposed to distribute electrical power to said electric power consuming devices, comprising a source of electrical power of at least two different voltages including a first voltage and a second voltage, and circuitry including ground conductors, first conductors connected to said first voltage, second conductors connected to said second voltage, and third conductors connected to said electrical power consuming devices;

    a communications system comprising data cables communicably connected to said microprocessor, said radio frequency receiver, and said data handling apparatus, wherein at least one of said microprocessor, said radio frequency receiver, and said data handling apparatus is located in said airframe and at least one of said microprocessor, said radio frequency receiver, and said data handling apparatus is located in said data handling module; and

    a connection arrangement including stationary terminals disposed in one of said airframe and said data handling module, and at least one free data cable and free power conductors disposed in the other one of said airframe and said data handling module, wherein said stationary terminals include a ground power terminal connected to a said ground conductor, a first power terminal connected to at least one of said first conductors, a second power terminal connected to at least one of said second conductors, and a stationary data terminal communicably connected to at least one of said data cables of said communications system, and said free power conductors are matingly compatible with said first power terminals and said second power terminals, and said free data cables are matingly compatible with said stationary data terminal, and said free power conductors complement said ground conductor connected to said ground terminal, said first conductor connected to said first power terminal, and said second conductor connected to said second power terminal to complete power circuits extending between said source of electrical power and said power consuming devices when said free power conductors are connected to said ground terminal, and at least one of said first power terminal and said second power terminal, and said free data cables complement said data cable attached to said stationary data terminal to complete a communications link extending between said microprocessor and at least one of said radio frequency receiver and said data handling apparatus when said free cable is connected to said stationary data terminal.
