...and then two hours later, at about 10:00 a.m. CDT, in England, London City airport was evacuated due to a chemical spill...

The morning of Friday, October 21, when those two incidents happened, is a multiple of 48 days after my September 25, 1989 dream which showed an aviation disaster and the headline "BLOW LOAN 48 HOURS", the dream took place while US President George H.W. Bush was addressing the U.N. and asking for an international Chemical Weapons Treaty (ban)...and furthermore, that morning (and thus the morning of Friday, October 21, 2016) was a multiple of 48 days after the Chernobyl Ukraine nuclear plant disaster on the morning of Saturday, April 26, 1986! Reportedly, "Chernobyl" means "wormwood" (bitter, poisonous) in old Ukrainian, and definitely, the Hebrew/biblical word for wormwood is "lo'an"...

There are several biblical passages which probably help explain the BLOW LOAN 48 HOURS dream, a description of which I posted online early on Monday, September 10, 2001, and then again in March of 2004, here: http://www.surfingtheapocalypse.net/forum/index.php?id=849

Jeremiah 9:15 and also 23:15 warn that a certain type of collective wrongdoing incurs a dose of wormwood
http://biblehub.com/jeremiah/23-15.htm ....and then Jeremiah 51:1 describes a "destroying wind" also as a chastening in response to a certain type of collective wrongdoing.

Hmm, that's about it for now...I managed to fit in the preceding sentences and links a full enough explanation of why I don't believe Friday's nearly-simultaneous chemical spill evacuations in the U.S. and U.K. aren't a meaningless coincidence.
