A friend of mine may have seen the same plume or a similar one. He said what he observed looked like a mushroom cloud!
Update- I'm posting from Harrisburg. Went outside for a break and saw one very large mil. helicopter heading south-south east from the capitol.
I came back in and looked at a map in a phone booth - that does seem to be the direction of TMI.
So many of these nuke plants are next to rivers. I imagine we have to patrol both the water and the sky.
However, the problems in the Arizona plant yesterday appear- from their reports- to be more internal. I'll post the excerpt from the Homelandsecurity.com Intel alert.
