The news that has confirmed the launch of the Unha-3 rocket was announced by South Korea’s YTN television network around 22.52GMT.
As soon as the news spread, I checked Planefinder.net to see if there was any aircraft (using ADS-B) along the missile’s projected flight path and found a Korean Air KAL8658 overflying the East China Sea at 580MPH and FL390.
I took the following screenshot with a certain concern….
However, shortly after the launch was announced, U.S. officials said that the missile was believed to have crashed into the sea 90 seconds into flight.
