I first heard it was chlorine gas.
Now reports are saying sarin or chlorine and sarin.

• I'm a water plant operator who works with chlorine gas. Some facts about chlorine make it hard to believe chlorine was used.
  • Witnesses report a yellowish mushroom cloud. That is the proper color. Chlorine is a yellowish-green gas.
  • However, it is heavier than air, so I'm having a hard time believing there was mushroom cloud. I suppose anything is possible if a bomb was used.
  • If you take a breath of chlorine gas you are dead.

I personally believe this was just another false flag. If there actually was gas released, Syria did not do it. Probably our CIA and Israel Mossad...
