Truthdig editor’s note: The following article about the alleged nerve agent attack in Khan Shaykhun [Sheikhoun], Syria, earlier this month corrects an important error in the report by Theodore A. Postol published by Truthdig on April 19, 2017.
Local journalist in Khan Sheikhoun, Syria reports from site of an alleged sarin gas shell airstrike on April 4, 2017 (YouTube screenshot)In my report published April 19 on Truthdig, I misinterpreted the wind-direction convention, resulting in my estimates of plume directions being exactly 180 degrees off. This article corrects that error and provides important new analytic results that follow from correction of that error.
When the error in wind direction is corrected, the conclusion is that if there was a significant sarin release at the crater as alleged by the White House Intelligence Report (WHR) issued April 11, the immediate result would have been significant casualties immediately adjacent to the dispersion crater.
Analysis using weather data from the time of the attack shows that a small hamlet about 300 meters 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 a long additional distance for it to have dissipated before reaching any other population center.
Video taken on April 4 shows that the location where the victims were supposedly being treated for sarin exposure is incompatible with the only open space in the hamlet that could have been used for mass treatment of victims. This indicates that the video scenes where mass casualties (the dead and dying) were laid on the ground randomly was not at the hamlet. If the location where the bodies were on the ground was instead a site where the injured and dead were taken for processing, then it is hard to understand why bodies were left randomly strewn on the ground and in mud as shown in the videos.
The conclusion of this summary of data is obvious—the nerve agent attack described in the WHR did not occur as claimed. There may well have been mass casualties from some kind of poisoning event, but that event was not the one described by the WHR…

At the Congressional Office of Technology Assessment, he advised on missile basing, and he later was a scientific consultant to the chief of naval operations at the Pentagon. He is a recipient of the Leo Szilard Prize from the American Physical Society and the Hilliard Roderick Prize from the American Association for the Advancement of Science, and he was awarded the Norbert Wiener Award from Computer Professionals for Social Responsibility for uncovering numerous and important false claims about missile defenses.
