spanners you would probably be best placed to answer, but isn't that fundamentally a chop, strenghten, gut, install, and D-check? Not trying to sound flippant about the work that is done, but there was only one in the last FY. I really can't see where the money has gone. Like I said US$260,000 a day EXTRA, every day, is a lot of $ (USD180 a minute EXTRA in case you were wondering)
