@JPB,
I think the whole process will take a while... getting the capsule set up, getting the paramedic in it, getting him down there (maybe 20 minutes), then he/she examines people to make sure they're ready to go up, then get them situated, then pull the first guy up.
Just from the pictures it looks twilighty now. (Have CNN on.)
The article above said they planned to start at 5 EST (6 PM their time), it's almost two hours past that now. Maybe "start" just meant start the preparations, which might be mostly invisible.
edit: turned back to the TV and looks like there's a guy actually in the capsule now (ready to go down) and the CNN supertitle is "ready to begin"
