The airline said overnight that the flight from San Francisco to Hong Kong reported witnessing the apparent re-entry of the ICBM that North Korea launched before dawn last Wednesday. The Hwasong-15 missile is capable of reaching all parts of the US.

It was in the air for 53 minutes. The Hwasong-15 intercontinental ballistic missile demonstrated a greater range than other missiles North Korea has tested. One expert estimated its range at more than 13,000 kilometeres if launched on a standard trajectory, which would put Washington DC within reach.

The flights, one from San Francisco and the other from Los Angeles, were both headed for Incheon, the main airport serving Seoul, South Korea. Experts say the chance of a missile test hitting a civilian airliner is very low. North Korea likely chooses splashdown points for each stage that avoid airline routes, said Vipin Narang, an expert on nuclear strategy at the Massachusetts Institute of Technology. “The problem is if the test goes awry in any way, and debris starts falling in ... more heavily trafficked areas,” he said in an email. “That would still be low probability but more risky.” Kim Jung Un visits tire factory for missile vehicle1:08 North Korea's leader inspected Amnokgang Tire Factory where they make wheels for missile vehicle, like the
