Did a failed North Korean ballistic missile fall near Pyongyang? = South Korea

North Korea launched two ballistic missiles, 10 minutes apart, on the 1st, and there is speculation that the second missile may have fallen inland from North Korea, such as near Pyongyang.
South Korea's Joint Chiefs of Staff said on the same day, "Our troops received missiles fired toward the northeast from the Changyong area of Hwanghaenam-do at around 5:05 a.m. and 5:15 a.m.
The missiles launched by North Korea this time are believed to be the Hwasong-11 type KN-23, which is being called the "North Korean version of Iskander."
The head of the Public Information Office of the Joint Chiefs of Staff said at a regular press conference that day, "The second North Korean missile may have flown abnormally in the early stages."
"If it exploded during the launch, the debris may have fallen inland," he said. Some have suggested that North Korea's second missile may have crashed near Pyongyang.
A military source said, "The second missile disappeared from radar after flying over 120 kilometers, so it is difficult to pinpoint the exact location of its impact," but added, "It went toward Pyongyang."
I think that's a possibility," he said.
