Abstract
Abstract A cargo box especially adapted for use in housing aircraft cargo, which box is made up of a base or pallet, sides, a top or cover, and ends, all of which may readily and expeditiously be assembled to provide a watertight box which is at once able to withstand relatively heavy gravity loads incident to operation of the aircraft while at the same time being extremely light for the result produced. The construction of the box is such that it may readily be knocked down upon arrival at a destination and reused.
