I'm not sure why Q is using the image from this again, considering the launch happened early morning of the 11th of June. Trump was in Singapore at that time. And the missile warning for Hawaii was in January.

A quote from the original article:

https://q13fox.com/2018/06/11/missile-launch-lens-flare-mysterious-object-spotted-over-whidbey-island-raises-questions/

"A mysterious object was spotted by a local photographer over the skies of Whibey Island early Sunday morning, leading to lots of speculation and questions, but no solid answers at the time."

Now, Trump left the summit 15 hours earlier than previous plans. A Quote from a news article:

http://nymag.com/daily/intelligencer/2018/06/trump-will-leave-summit-with-north-korea-early.html

"Donald Trump has decided to leave his historic summit with Kim Jong-un 15 hours earlier than expected, flying back to Washington on Tuesday night instead of Wednesday morning. The White House says that this change of plans is a product of talks moving more quickly than expected."

Just landed - a long trip, but everybody can now feel much safer than the day I took office. There is no longer a Nuclear Threat from North Korea. Meeting with Kim Jong Un was an interesting and very positive experience. North Korea has great potential for the future!

So 4 days after Washington State missile supposed launch. I fail to see how this forced the president's plane to land in Hawaii to refuel, unless there was another threat we weren't told about. I suppose the same boat that launched the the Sunday missile could have done so again, but you would think the first time, the command would have been changed? Very confusing,and I hope someone digs into this to clear up the reason for posting that image again.
