The mosquito aircraft targeting the Buna area in the late morning of 25 August 1944 had at least two vertical (but slightly shifted) cameras still on when passing over the nearby Auschwitz-Birkenau site. The cameras were taking pictures every few seconds. Given the height & speed of the aircraft and the comparable short interval time, the frames of each camera are largely overlapping and objects on the ground were captured three times by each camera. With image processing programs, animated gif files can be created revealing the movement of groups of people or single vehicles, which took place within those few seconds.
This overview picture of 25 August 1944 shows the various locations with significant movement of vehicles or groups of people in Auschwitz-Birkenau.
Image number 1 (outside crematoria 2 and 3). The photographs show two formations of people on the left side turning towards the road between crematoria 2 and 3.
Image number 2 (camp section BIa-b). Shows a long formation of people crossing the road between camp section BIa and BIb. Another formation is lined up and entering the delousing facility on the right side.
Image number 3 (camp section BIIb). Considerable traffic on the eastern part of the road crossing the camp section BIIb
Image number 4 (Birkenau ramp). Some traffic on both sides of ramp.
Image number 8 (camp section BIIe). Prisoners lining up between the barracks on the left side.
Image number 9 (camp section BIIc). Heavy traffic on the road passing through camp section BIIc.
Image number 10 (camp section BIII). People leaving and entering camp section BIII.
Image number 11 (SS compound). Formations of people walking on roads.
Image number 12 (Road between camp and SS compound).
By the way, the aerial photographs taken two days earlier, on 23 August 1944, show a long formation of people walking on the road between crematoria 4 and 5. The formation is about 160 m long, probably several hundreds of people from one of the Lodz transports arriving these days. Their destination is crematoria 5 or the central sauna, depending on if the people have been selected as fit or unfit for labour at the ramp.
Another interesting thing is that activity and work was going on at the Bunker 2 extermination site between 23 and 25 August 1944. Structures and discolorations change within the pentagon shaped extermination site as well as between the two undressing barracks.
