How can I independently verify that a missile was launched by North Korea and that it flew over Japan?
I live in Japan and this morning Japanese and Western news were full of articles about North Korea having fired a second missile over Hokkaido (Japan). Neither my colleagues nor I have seen or heard a missile. Nor does googling reveal any pictures taken by the public from this morning, nor from the missile on the 29th of August 2017.
We discussed the conspiracy theory that certain players are uncertain about how long the USA will back Japan and that they want to sway the Japanese public opinion towards reintroducing a scalable military force. Fake news is fabricated by Japan and its allies. Chinese and Russian national news agencies do not seem to mention the missiles. Hence, we would like to independently verify the missile launches and trajectories. For example from public data from weather stations or other.
This question is not about whether the conspiracy theory in the last paragraph is true or not!
