Optical alignment of the hold down posts on the mobile
launcher platform is in progress. The left and right aft skirts
have been removed from the mobile launcher platform. Earlier this
week, gauges attached to the aft skirts and hold down posts gave
readings about the loads that are not understood. The concern is
that the posts are not aligned properly. The aft skirts are
scheduled to be restacked on Saturday. Schedule impacts are cur-
rently being assessed.
