This kit is in 1/700 scale. It includes 2x Boeing KC-767 Aerial Refueling Aircraft. They are connected as a single sprue by wires under the main body of the aircraft. Once the wires are cut the aircraft do not require any finishing. This Military version of the Boeing 737-700 has been altered for airborne refueling.
According to Wikipedia: "The Boeing KC-767 is a military aerial refueling and strategic transport aircraft developed from the Boeing 767-200ER. The tanker received the designation KC-767A, after being selected by the US Air Force initially to replace older KC-135Es. In December 2003, the contract was frozen and later canceled due to corruption allegations."
