Abstract: A pallet interface system for supporting a Container Roll in/Out Platform (CROP), flatrack or ISO container within an aircraft, such as a C-17 aircraft. The interface system includes two independent, identical interface pallets which are coupled together by flexible cables. The cables have lengths which enable the two interface pallets to be spaced apart a precise distance so as to be able to support a CROP, flatrack or ISO container. The interface pallets are of small enough dimensions and weight such that same can be manipulated by one or more individuals, thereby obviating the need for a crane to be employed to lift the load onto the pallets before the loading process can begin. Each pallet has a plurality of ISO locking assemblies which allow a CROP, flatrack or ISO container to be locked thereto. Each pallet also has a 463L cargo system edge structure which permits it to be locked to the rails within the C-17 aircraft.
