A spokesman told Fox News on Thursday that fears of a North Korean missile that accidentally destroyed a passenger plane during one of the uncoordinated and uncoordinated rocket launches by Kim Jong Un changed its course of flight this year .
Singapore Airlines, in response to the launch in North Korea of an intercontinental ballistic missile in July, changed their route for flights between Incheon, South Korea and Los Angeles, California. The new route avoided the northern part of the Sea of Japan, the spokesman said.  "The safety of our customers and crew is our number one priority and we continuously monitor the areas over which we fly," the spokesperson added.
While Singapore Airlines has continued to avoid the area, a flight crew on a different airline reported last Wednesday's release of North Korea's ICBM. Cathay Pacific said Monday that passengers and crew on the flight from San Francisco to Hong Kong reported seeing the ICBM Hwasong-15 flight.
The missile was far from the plane, and the plane's operation was not affected, Cathay said, adding that it had informed other companies and relevant authorities.
"At the moment, no one is changing any route or operating parameters," the Hong Kong-based airline said in a statement. "We remain vigilant and [will] we review the situation as it evolves."
Korean Air pilots on two different aircraft also reported seeing flashes of light believed to be the North Korean missile while flying over Japan, airline spokesman Cho Hyun-Mook said. The flights, one from San Francisco and the other from Los Angeles, were headed to Incheon, the main airport serving Seoul, South Korea.
Singapore Airlines said it was aware of the reports on the missile sighting of the Cathay Pacific flight crew. closely monitoring the situation "
The chances of one of Kim's missiles hitting a civilian plane are very low, experts said. North Korea is likely to choose spill points for each stage that bypasses air routes, said Vipin Narang, an expert on nuclear strategy at the Massachusetts Institute of Technology.
"The problem is if the test fails in some way, and the debris begins to fall … in … areas with the most traffic of people," he said in an email. "That would still be low probability but more risky."
