1. In an airport network wherein a plurality of aircraft are stowed at each of a plurality of site airports, a method of securing the aircraft against vandalism and theft, said method comprising the steps of:

  • (a) detecting the occurrence of an unauthorized intrusion into or other alarm condition aboard one of the aircraft at a site airport;

    (b) transmitting a uniquely identified coded signal from the aircraft in response to the detected condition;

    (c) receiving the transmitted signal at the site airport where the transmission was made;

    (d) comparing the unique identifier of the received signal to a list of identifiers for aircraft stowed at the site airport to determine if the transmission originated from an aircraft normally stowed at the site airport;

    (e) if the transmission originated from an aircraft not normally stowed at the site airport, creating a record of the received coded signal in a site main computer and making the record available to a central facility computer coupled to each of the site main computers for tracking and location of an aircraft confirmed to have been stolen from another one of the site airports in the network;

    (f) if the transmission originated from an aircraft normally stowed at the site airport, interpreting the coded signal to determine the nature of the condition aboard the aircraft; and

    (g) initiating remedial action appropriate to the nature of the condition indicated by the coded signal.
