This is fascinating to think about! Thank you for the article.

I would like to bring your attention to your first paragraph, in which you state: "...there was a test of the "Emergency alert Wireless system" to be conducted on 11/20/2018 at precisely 2:18 PM."

The test was originally scheduled for September, not November. This is such great info to think on, and don't want others to be distracted by a simple typo.
