Shuttle Atlantis finally managed to get off the launchpad.
As of yet I have not heard of any ECO sensor issues. I doubt it's because there weren't any. It's more likely not an issue because of the amended flight rules that allow shuttles to launch with not having all 4 ECO sensors on the ET tanks fully functioning.
With all these delays I have to ask the question will the ISS even be completed on time? I can imagine if 2012 rolls around and NASA is still fooling around in low earth orbit instead of following the VSE that more than one congressman will call for the station to be scuttled and retired.
