For scale: Hawaii is not only ten times as far away, that missile landed in the sea west of japan.
The hysteria displayed both by the FAA and in this thread is kinda shocking. I work with the military in Japan. Every time a North Korean missile flies into/over Japanese territory we get a warning about it...and then go about our business as usual. We can usually see their flight trajectories on our Common Operational Picture. This one was not significantly different from the dozen or so previous incidents. No idea why people in the States shat a brick and grounded civilian aircraft, especially if NORAD didn't concur with such an action.
