Via the Washington Post, North Korea has taken a significant step toward perfecting an intercontinental ballistic missile system.
The Hwasong-18 ICBM reached a height of more than 3,800 miles during its almost-vertical flight on Wednesday — twice as high as the first launch of this kind of missile in April and 16 times as high as the International Space Station. It flew for a record 74 minutes.
North Korean state media said the Hwasong-18 flew as high as 4,131 miles, consistent with Japanese estimates.
