Channel NewsAsia found out that Singapore Airlines (SIA) has taken steps to reroute its Seoul-Los Angeles flights since July this year, following Pyongyang's July 27 missile launch into the Sea of Japan. Korean Air hasn't specified how close its flight was to the missile.
An airline crew traveling from San Francisco to Hong Kong claim they had a chilling, front-row seat to North Korea's latest missile test over the Sea of Japan.
US officials told CNN that the re-entry vehicle likely failed during North Korea's most recent missile test, and the crew of a Cathay Pacific flight claims to have seen the missile explode during re-entry, although David Wright, a senior physicist with the Union of Concerned Scientists, suspects that the crew actually saw stage separation and second-stage ignition during the ascent. Hwasong-15, according to North Korean state media, reached an altitude of 4,475 kilometers (2,800 miles), and put the "whole" United States mainland in its range. The airlines witnessed the blow-up and disintegration of the missile close to their location.
Minutes later, the pilot of another Korean Air plane reported seeing a similar flash of light, airline spokesman Cho Hyun-mook said, as cited by AP. "We remain alert and (will) review the situation as it evolves".
Although airlines have not announced any moves to change routes following the most recent launch, Lufthansa, Swiss Airlines, and Scandinavian Airlines changed their routes in August following Pyongyang's first successful ICBM launches in July, the Financial Times wrote at the time.
Marco Langbroek, a space expert who tracks North Korea's missile program, told CNN he noticed something unusual about the stars in images taken from opposite sides of the missile launch.
The International Civil Aviation Organization in October had condemned the missile tests as it threatened the safety of commercial flights but it had little effect on the North Korean regime. Such notices are issued to warn pilots and airlines of potential risks during their flights. The chances are "billions to one", aviation safety analyst David Soucie told CNN.
