Cargo loads are frequently carried by being slung under a helicopter and carried by its cargo hook. One of the problems arising from this type of transportation is that the load is reasonably unstable relative to the helicopter, and its instability precludes certain operations which would otherwise be possible. The invention provides a device that creates the desired stability. There is described a load frame for external attachment to a helicopter by its cargo hook. The frame has a base from the upper face of which radiates a plurality of arms which engage the underside of the skids of the helicopter. By means of a winch mounted on the base, the load frame can be snugged up into a stable flight position beneath the helicopter with the arms firmly engaging the underside of the helicopter skids. There is also disclosed a reel for attachment to the load frame which conveniently can be used to pay out a fire hose or the like from the helicopter in flight.
