North Korea Tests Longest Lasting Missile

on Tuesday, North Korea tested a missile that flew about 1,000 km and landed in the sea east of Japan, but crested at 4,500 km above Earth's surface. This makes it the highest and longest lasting flight North Korea has ever achieved. physicist David Wright recently wrote that North Korea's latest missile could likely fly 8,100 miles on a normal trajectory — enough to hit the entire continental US. it's still unknown how credible the latest launch was.
