Abstract: A load supporting assembly structured to support and retain cargo intended to be loaded on and transported by a common commercial carrier, such as an aircraft, wherein the supporting assembly may be in the form of a pallet or alternatively a container having a base panel, side panel and one or more additional panels. Each of the panels include a peripheral flange or like portion extending at least along a majority of the length thereof, which is disposed and configured for fixed attachment to one or more track segments or one or more attachment members. The attachment members are disposed and structured to interconnect the various panels into a predetermined shape, without the use of conventional fasteners or connectors, dependent on the type of common carrier in which the load supporting container assembly is to be loaded.
