We flew the ergo arm to the south bay for Betsy. Disassembled the E module and moved to the north side of ham 4, started disassembly of the work platform that was around bsc 1 for install at bsc 2. Need to remove (with approval granted from Hugh) the horizontal hepi accuators on the south side of bsc 3 to allow installation of the work platform section between bsc 2 & 3. These will be unbolted and rolled down will still being secured with the current hepi bolts. (This same thing was done on bsc 2 for some clearance issues.) Also assisted Hugh/Eric with hepi install.
