In South Carolina that is the view that we're looking at right here as we now approach. We have a minute 35 seconds to the next totality which is right where I'm standing. It of course Charleston we just wash it in Columbia the State Capitol and what an extraordinary sight they saw in that stadium. And I've got to tell you I'm surrounded by an entire an incredibly gifted crew. But no one is looking at me right now they are looking at the sky as they should be they are capturing the moment they all have the glasses on. And we are standing. On the people's building corporate enough air Charleston. And I mentioned earlier the program president tapped into disparate. The 1920s. Because it was one of the best views in this great American city and now we are taking it. The great American it lists. The final stop at a big city at least up here in the continental United States before. It's great American it clips heads out to sea it is pitch black. You've been here. Cheers throughout the city you probably can't here at home but you can hear it as we stand on the roof top of this building. We have gone into complete darkness. And we have watched this play out in so many cities across this country before you got to us. And there's nothing you can do to the airport it is just breathtaking. People or applauding. Throughout the ball over. It was so excited and so welcoming. Everyone who helped put this production together on this rooftop. If we can look up. And we could see. That we are now at a total eclipse. Can see the corona around. The sun. It's one of those rare moments. We are we here on earth. We can make and I can actually see that outer atmosphere of the sun.

NBC to play over and over again. The diamonds ring in the and Bailey's beads obviously named after Francis Bailey. The greatest drummer who first points.
