Latest on pad damage
Bricks with corroded anchor tabs on them:
http://www.nasaspaceflight.com/content/?cid=5439 _*Pad Damage Investigation Latest: *_the pad damage sustained by Pad 39A has revealed the metal tabs anchoring the bricks to the flame pit are severely corroded and or missing, according to investigation notes on Tuesday. Tens of exclusive images of the damage sustained by Pad 39A since Sunday have given an insight into the amount of work required to get the pad back to an operation status. However, the opening investigation notes, also acquired by L2, have provided the first documented overview of the immediate work ahead. 'A 100' X 20' section of the east wall of the north flame trench sustained severe launch damage,' investigation notes revealed. 'Broken sections of the flame trench wall were scattered from the flame trench to the pad perimeter fence. The area is under controlled access until the debris is removed. The wall is being inspected by USA Structures and NASA Structures engineers, who have already noted that the pad's 3'' by 4'' metal tabs that are used for anchoring the bricks to the concrete are 'severely corroded and or missing.' The remaining brickwork may have to be removed, as the wall is 'judged to be unstable at this time,' though the process of replacing the bricks is still being evaluated. 'The bricks from the wall are Apollo-era and are no longer available; as a result, the team is consulting with the manufacturer and repair options are being investigated,' added the investigation notes." Also, the damaged area has asbestos in it, so now they have a hazardous materials problem to deal with: http://www.wcsh6.com/news/article.aspx?storyid=88594 Pat |
