The midrange ballistic missile that was fired over Japan by North Korea was done so under what appear to be new methods by the Hermit Kingdom.
Tuesday’s launch was the first-ever reported from Sunan, which is home to Pyongyang's international airport. Some outside observers wondered if North Korea had launched a road-mobile missile from an airport runway — something South Korea's military couldn't immediately determine.
The airport's runways could provide the ideal space to launch a road-mobile missile like the Hwasong-12, while also demonstrating that the North can launch its missiles from anywhere, according to Moon Seong Mook, a former South Korean military official and current analyst for the Seoul-based Korea Research Institute for National Strategy.
North Korea will no doubt be watching the world's reaction to see if it can use Tuesday's flight over Japan as a precedent for future launches.
