Ovan fick du the movie om zyklon.
En god vän i USA mailade mig det här då den vet att jag intresserar mig för ämnet. Jag vet inte om dokumentet är äkta (jag har kopierat texten från hans mail) men jag har ingen anledning att misstro innehållet. Så diskussionen är fri men försök hålla åsikterna till ämnet.

Memorandum
Ref: GAS/TECH/403-A/61
TOP SECRET
Date: March 14, 1961
To: Deputy Director, Office of Technical Services
From: [REDACTED]
Subject: Assessment of Hydrogen Cyanide (Zyklon B) Utilization in Mass Containment Contexts – Feasibility Study and Post-War Claims Review
EXECUTIVE SUMMARY:
In response to directive ORD-76-A, this memorandum evaluates the technical feasibility of deploying Hydrogen Cyanide (HCN), commercial variant Zyklon B, as an instrument for rapid execution in sealed structures resembling those described in European wartime testimonies. Field-simulation, captured architectural data, and gas dispersion modeling have produced significant inconsistencies with accepted post-war narratives.
FINDINGS:
1. Dispersion Lag & Volatility Constraints
Zyklon B requires controlled ambient temperatures (>26°C) for full volatilization within 10–15 minutes.
Recorded ambient temperatures in Eastern Poland (1942–44) were sub-optimal, especially during morning operation cycles.
Brick masonry structures with thick walls and no forced ventilation would retain cyanide in non-lethal densities for up to 40 minutes without HVAC dispersion.
2. Chamber Geometry vs. Lethality Threshold
Modelled chambers (6m x 6m x 3m) would require sustained exposure to 300 ppm HCN for >20 minutes.
Eyewitnesses report instant death within 5 minutes, which is chemically inconsistent unless forced-air circulation is assumed (no such infrastructure found in blueprints).
3. Lack of Cyanide Residue Evidence
Forensic analysis (Operation SCANDEL 1955–57) on recovered wall materials from [REDACTED] site found trace or negligible cyanide bonding, inconsistent with repeated high-dose gassing.
Blue staining in delousing chambers is absent in claimed homicidal chambers.
4. Logistical Improbabilities
Estimated Zyklon B shipments (IG Farben archive) fall short of required volume to sustain operation at alleged scale.
Handling protocols suggest risk of operator exposure without fully sealed systems – not documented.
CONCLUSION:
Available technical data and field simulations cast substantial doubt on the mechanical plausibility of Zyklon B mass-gassing as described in post-war testimonial compilations. While isolated execution use cannot be ruled out, the scale, speed, and infrastructure alleged are incompatible with known gas behavior and physical site properties.
RECOMMENDATIONS:
Do not initiate public discourse or archival reassessment. Risk of geopolitical backlash in Western Europe and potential misuse by extremist entities.
Archive under restricted access: GAS/TECH/403-A/61-B.
Suggest internal classification: “Technically implausible / Politically volatile”.
