That dot is some kind of balloon or something like that. Developing . . .
Go to cnn.com for a live feed (or dang near anywhere else).
Edit: Youtube video of that thing in flight. (Thanks emailer)
Edit: At 2:30 it landed but there is no boy! Either he was never in there or he jumped somewhere along the way. We gove the Great 2009 Mystery of the Balloon Boy!
