Abstract: A collapsible container has a top frame and bottom frame with folding walls having predetermined fold lines therein. The container has a closed position which is a flat platform configuration. In this configuration the walls are folded within the platform which may be used as a pallet for piece goods. The container has an open position where the top frame is raised and the container can be integral with a wheeled vehicle and used as a bulk carrier. Thus the container can be used for one shipment as a pallet for piece goods and for a next shipment as a bulk carrier.

Abstract: A fire bomber aircraft has an elongated discharge chute which communicates with the outlet opening of liquid tank and a discharge end disposed a substantial distance below the input end. The discharge end opens from the aircraft to atmosphere such that upon movement of the closure door of the drop tank to an open position, liquid will flow through the outlet opening to form a falling stream which will accelerate to a substantial velocity before it is discharged through the discharge end to the surrounding atmosphere to thereby reduce the erosion of the body of liquid which is discharged.
