The story claims that Jews were gassed at Auschwitz/Birkenau in underground morgues which were supposedly adapted by cutting openings in the roof of the morgue (the roof extended just above ground). These openings (holes) were then supposedly fitted with curious wire mesh devices which are supposedly used to lower in the insecticide, Zyklon-B, which is said to have been the gassing agent. The story says that these openings protruded above the roof. Yeah I know, it's looking stupid already.
Here we have a wartime aerial photo that Believers claim show these openings on the roof of the morgues, hence supposed proof of gas chambers at Auschwitz/Birkenau. Revisionists claim that these crude marks were added to photos because the original photo obviously did not show the alleged openings/holes/gas chambers. IOW, the photos were tampered with.
The Believers claim the openings/holes are made to look larger and elongated due to shadows that would be result of the protusion of the alleged Zyklon-B insertion apparatus.
Here is what is claimed to be an Zyklon-B insertion apparatus/column, notice the height of the section which would supposedly protrude above the 'gas chamber' roof.
Return to the aerial photo and look at the size of the 'shadows'. Given the claimed size & height of the alleged Zyklon-B openings, the 'shadows' are an impossible length and angle given the height of the sun and the surrounding real shadows.
Here is the aerial photo from above with devastating information overlayed.

Prof. van Pelt writes [p. 295]:
These columns were connected to small holes that penetrated the concrete ceiling of the gas chamber, which opened to four small "chimneys" for lack of a better word. These are visible on one of the photos of crematorium 2 taken by the SS during construction, the aerial photos taken by the Americans in 1944 […]
Is Prof. van Pelt an expert for analyzing photos? If he is, than I might add the following conclusions of analyses of the photos van Pelt refers to:
1. Analysis of a section of an air photo of the Birkenau camp taken by a Canadian airplane August 1944.
* The alignment of the patches referred to by Prof. van Pelt s "chimneys" does not agree with the direction of the shadow cast by the crematorium chimney!
* On a photo from September 13, 1944, the patches on crematorium III retain their direction and shape even though the position of the sun has changed!
* On that same photo the patches on morgue 1 of crematorium II are missing!
* The length of the patches would corresponds to objects 4.5 ft. wide and rising 10 to 13 ft. above the roof – in other words, large objects, not the approximately 20-inch-high hatches attested to by witnesses.
* These jagged, irregular patches cannot be shadows cast by perpendicular, straight input hatches.
This confirms the fraudulent nature of the absurd 'holocau$t' Auschwitz gas chambers claims. It's just not that difficult.
So, if the crudely drawn on black marks cannot be Zyklon-B insertion holes with shadows as is alleged, then what will Believers claim they are next?
Revisionists are just the messengers, the absurdity of the 'holocaust' is the message.
