The closest shave was on Nov 29, where crew on at least three commercial flights from Korean Air and Cathay Pacific reportedly saw the North Korean missile in the air before it blew up near their location. Korean Air said the pilots on two of its flights bound for Seoul "saw a flash and everyone is assuming it should be the missile because of the timing".
An official at the Ministry of Land, Infrastructure and Transport said, "It appears that Singapore Airlines is flying over Busan and the east coast of Japan rather than flying through Gangwon Province and the East Sea".
The crew of the Cathay Pacific Airways flight says they witnessed the rogue nation's latest weapon break apart and explode as it traveled through the sky early Wednesday morning on November 29.
North Korea has tested an Intercontinental ballistic missile, which posed no threat to the U.S. and its allies, said the Pentagon.
"We have been in contact with relevant authorities and industry bodies as well as with other carriers". For the time being, there are no planned changes to existing Cathay Pacific routes. "We remain alert and (will) review the situation as it evolves".
The North has conducted a flurry of missile tests this year in defiance of repeated global protests, including from aviation authorities.
According to the Committee of chiefs of staffs of armed forces of South Korea, the missile launched from the landfill in the North Korean city of Pinson in the province's toll.
Under the guidelines of the International Civil Aviation Organization-a United Nations agency that oversees air safety-nations launching threats to air safety must "issue risk advisories regarding any threats to the safety of civilian aircraft operating in their airspace".
South Korea says Pyongyang regularly fails to issue notices to airmen when conducting missile launches.
Travelers who are concerned should know the chances of an airplane colliding with a missile are extremely low: One safety analyst estimates that it is less than a billion to one.
