Several years ago, there was a YouTube video which showed Fred Leuchter, Jr. speaking about the gas chambers at Auschwitz. Since then, the video has been taken down. However, you can read what Leuchter wrote about the Holocaust gas chambers here.
Leuchter’s life was ruined after he testified in the trial of a Holocaust denier in Canada a few years ago, after which, he apparently went into hiding, in fear of his life.
This quote is from the website, cited above:
…. a very believing engineer sat at his desk working one snowy January afternoon in 1988, when the telephone rang. This very believing engineer [Fred Leuchter] was about to receive a very shocking history lesson, one which would cause him to question that 50-year-old Holocaust lie and the application of that lie to generations of children. “Hello, this is Robert Faurisson” — and that very believing engineer would believe no more.

Construction of these facilities shows that they were never used as gas chambers. None of these facilities were sealed or gasketed. No provision was ever made to prevent condensation of gas on the walls, floor or ceiling. No provision ever existed to exhaust the air-gas mixture from these buildings. No provision ever existed to introduce or distribute the gas throughout the chamber. No explosion-proof lighting existed and no attempt was ever made to prevent gas from entering the crematories, even though the gas is highly explosive. No attempt was made to protect operating personnel from exposure to the gas or to protect other non-participating persons from exposure. Specifically, at Auschwitz, a floor drain in the alleged gas chamber was connected directly to the camp’s storm drain system. At Majdanek a depressed walkway around the alleged gas chambers would have collected gas seepage and resulted in a death trap for camp personnel. No exhaust stacks ever existed. Hydrogen cyanide gas is an extremely dangerous and lethal gas, and nowhere were there any provisions to effect any amount of safe handling. The chambers were too small to accommodate more than a small fraction of the alleged numbers. Plain and simple, these facilities could not have operated as execution gas chambers.
Note that virtually everything that Fred wrote is what I have been trying to communicate through my blog for over two years.
Except for one tiny detail: “the floor drain in the alleged [Auschwitz] gas chamber” is included in the reconstructed gas chamber that is shown to tourists, but this drain was originally inside a washroom in the gas chamber building in the main camp.
I previously blogged about the Auschwitz gas chamber floor drain here. I also blogged about the 6 floor drains in the Dachau gas chamber here. According to Fred, a gas chamber absolutely cannot have even one floor drain, much less 6 drains.
