earlier, i spoke to our seoul correspondent jean mackenzie, who gave us the picture from the ground. yes, so we were awoken this morning at about 6:30am or so, with the sound of the air raid siren, which is not common. we had messages to prepare for evacuation and we heard that the north, according to the south korean military, had launched a space launch vehicle. we think it's a spy satellite that north korea said they would launch in the coming days. within 30 minutes, residents in seoul had another announcement that the alert had been sent in error, they didn't have to evacuate, and could go about their day. what we have learned since is that north korea has launched this space vehicle, but it didn't come anywhere near seoul. they started to get reports that perhaps this rocket launch has failed but we cannot confirm that. that is something the south korean military is looking into at the moment. there have been many launches of all kinds of things from north korea over the past few months. is this space launch something people consider to be an escalation? it's considered to be s
