Cathay Pacific did not reply to a request for comment by publication time, but in a response sent out earlier to other media, the airline confirmed the incident and responded to the potential threat posed by North Korea's missile tests. At the time of the splashdown, the flight was about 60 to 70 miles (95 to 112 kilometers) north of where the missile landed, according to a review of the data.
JADGE is considered the brain of Japan's missile defense system.
In August, Air France said one its planes carrying more than 300 passengers may have come as close as 60 miles to a ballistic missile launched by North Korea.
Japan's defense ministry is requesting ten-point-seven billion yen which is over 94 million USA dollars in its 2018 budget to make the changes with hopes to fully deploy the upgraded version by 2022.
"Today. the crew of CX893 reported, 'Be advised, we witnessed the [North Korean] missile blow up and fall apart near our current location,'" Hoey said, according to a report in the South China Morning Post.
Their crew say they saw what appeared to be the test missile on re-entry as they flew towards Asia from the US West Coast.
"Though the flight was far from the event location, the crew advised Japan ATC (Air Traffic Control) according to procedures".
The International Civil Aviation Organization (ICAO) in October condemned North Korea for the repeated launching of ballistic missiles, saying they seriously threatened the safety of international civil aviation. Two South Korean planes also reported witnessing the missile test.
"The safety of our passengers and crew are our upmost priority and we will re-route our flights when necessary", it said.
Singapore Airlines has changed the route of its Seoul-Los Angeles flights because of North Korean missile tests over the Sea of Japan, the airline revealed Tuesday.
There is still some debate about whether the new missile represents a truly new classification of vehicle, as North Korea insists, or if it would be better viewed as an incremental upgrade over the Hwasong-14. "Operation remained normal and was not affected", the statement said.
The airline said at the time that it was expanding its no-fly zone over North Korea following the close-call.
A report from the Yonhap News Agency said the captain of a Korean Air flight approaching South Korea's Incheon Airport from San Francisco reported to ground control that he had seen a flash about one hour after the North Korean missile launched, The Telegraph reported.
