North Korea fired what’s believed to come to be the biggest and most powerful missile found in its arsenal that working day. Pyongyang stated the projectile flew as great as 4,475 kilometers (2,800 kilometers) before plummeting into waters off the western coast of Japan.

Singapore Airlines (SINGF) said its flights don’t travelling “near the missile trajectory” because of the way change it designed to avoid the northern part of the sea between your Korean peninsula and Japan.

The Cathay plane didn’t travel over that part of the sea either, according to flight tracking data. The airline stated that its flight was “far from the event site” and unaffected by the missile — but that the crew reported the sighting to air site visitors control in Japan in line with procedures.

“We have been in touch with relevant authorities and sector bodies and also with other carriers. Right now, no one is definitely changing any routes or working parameters,” Cathay stated. “We remain alert and review the problem since it evolves.”

Korean Surroundings didn’t provide information on the flights that saw the “flash,” or say where these were at the time of the event.

Singapore’s route change found in July came after an Air France (AFLYY) flight passed just east of the splashdown web page of a North Korean missile test, roughly five to ten minutes prior to the weapon hit the normal water.

Suggestions issued by the International Civil Aviation Business, a U.N. agency tasked with governing air safety, state that nations have the “responsibility to concern risk advisories regarding any threats to the safety of civilian aircraft working in their airspace.”

The chances of a plane staying struck randomly by a missile are “billions to 1,” according to CNN aviation safety analyst David Soucie.
