Analysis of the Times and Locations of Critical Events in the Alleged Nerve Agent Attack at 7 AM on April 4, 2017 in Khan Sheikhoun, Syria. Analysis using weather data from the time of the attack shows that a small hamlet about 300 m to the east southeast of the crater could be the only location affected by the alleged nerve agent release. The hamlet is separated from the alleged release site (a crater) by an open field. The winds at the time of the release would have initially taken the sarin across the open field. Beyond the hamlet there is a substantial amount of open space and the sarin cloud would have had to travel long additional distance for it to have dissipated before reaching any other population center.
