I am confused - I think I lost something in translation.
Korean
Thunderbirds are Go! remake?
"The missile flew 1,090 kilometers for 4,052 seconds at a top altitude of 6,248km before falling into the sea"
So 4,052 seconds is 67 and a half minutes - just over an hour. Nice.
6,248km in altitude is... beyond the exosphere. ISS orbits at between 320 and 440 km in altitude.
I think angry speaking Korean news lady might be spreading the bullshit.
But I hope she gets one of those nice watches the blokes got.
