two off to the side, numbers 5 and 6. then you have 4, 5 and 6. they were all offline when the tsunami hit last friday, but the problems developing there concern used fuel rods that are still stored on the site. chad myers, we're going to talk about some of those spent fuel rods because i know -- we know more or less where they are. but i want to begin with the pictures. we're finally seeing today, instead of that wider aerial shot, closer images of the damage. >> those closer images were quite startling. they literally looked like that was damage from the outside, like the tsunami may have caused that. that didn't happen. those buildings were intact after the earthquake and after the tsunami. that damage came from explosions or fires from within the buildings themselves. and then that long shot, it was fuzzy, hazy. you could see the steam. that was 30 kilometers away, 18 miles away, they had that helicopter out there taking that shot because they were afraid for the crew of that helicopter.
