The cargo bay floor of a Boeing C17 Globemaster transport aircraft at the 2012 Farnborough air show showing treadways and attachment cleats. The floor is shown in 'flat mode' for vehicle transport (complete with tie-down points), but the long narrow panels can be flipped 180 degrees to reveal rollers to accommodate palletised cargo. The C17 has a payload capacity of some 77 tonnes and a maximum gross takeoff weight of 265 tonnes.
