Memo To Commercial Airline Travelers --

It looks like if you plan to fly commercially next week, it may be best to do it by Tuesday, April 9, 2013 --- it looks like the Brits suggest Wednesday, April 10, 2013, could be a day of fireworks.

I don't know much about nuclear EMP, but I know enough that flying and nuclear EMP are not a good combination. 

North Korea recommending foreigners leave by April 10 -- the government can't guarantee their safety after April 10th.

The first thing one needs to do is start looking for historical events to determine why April 10 might be important. Unfortunately, wiki is geared for Western readers, and not much of interest to the Orient mind regarding this date.

However, this is noteworthy:

Kim Il-sung, the grandfather of the current North Korean leader, born 15 April 1912, died 8 July 1994, was the leader of the Democratic People's Republic of Korea, commonly referred to as North Korea, from its establishment in 1948 until his death in 1994. 

April 15: a nice birthday present in honor of his grandfather who was the "father of his country," much like George Washington was the father of our country. So, the warning that the country cannot guarantee anyone's safety after April 10 certainly fits.

Memo to self: update Google calendar.
