Abstract: An assembly for mounting, supporting, and releasably holding an angularly adjustable aerial photography camera that is to be used to take aerial reconnaissance photographs, while the assembly is detachably connected to the internal surface of a helicopter that is in stable flight and has an opening in each side. The assembly includes: a rectangular frame which carries the camera; another rectangular frame which carries ballast (i.e., a counterweight); and, a main frame to which the rectangular frames are releasably connected, and in which the frames are slidably movable in opposite directions simultaneously. In flight, the rectangular frames are simultaneously extended on each side of the center of gravity, and of the longitudinal centerline, of the helicopter, and through the opposite openings in the helicopter, with the camera extending out of one of the openings, and with the counterweight extending out of the other opening.

Abstract: An assembly for mounting, supporting and releasably holding a vertically positioned aerial photography camera, and an angularly adjustable obliquely positioned aerial photography camera, in an aircraft having a downwardly and outwardly opening ramp to which the assembly is removably attached, and also having an upwardly and inwardly opening tail door, where the ramp and the door are openable and closeable during flight of the aircraft. The assembly includes: a lower member subassembly in the form of a rectangular frame; and, two upper member subassemblies, each of which carries one of the cameras. These upper subassemblies are rectangular-like in form and are detachably connected to, and slidably movable horizontally above, the lower subassembly. In flight, with the ramp and the door open, the upper assemblies are separately extendable beyond the ramp, and aerial photographs may be taken.
