Diary '17/8/30. Intercepting system As always, I had an online English speaking class this morning. Continuing from yesterday, we talked about the missile from North Korea. He asked me if Japan has a missile intercepting system. I said we have one but it might not work for some kinds of missiles that fall at sharp angle like almost vertical. He was interested in how North Korea government motivates their army. I'm interested in it , too. Maybe they could resist the government in the near future. I went to work at 9 'o'clock. Today I made a bunch of 3D printed cases for my prototypes. Some of them need to be painted. It could be tough work but it always give me a joy. I will keep it up tomorrow.
