Apart from things weighing a bit more than the old overhead cranes were meant to lift....
, the 748 has been progressing well.
This is first hand info from the line, well one large section of it anyway, and more reliable than the 787 info, but apart from some draing and fastener issues and one set of drawings that were "forgotten", its going pretty well and some sections ahead of their BAR LINE or not far from it.
The way its going it will be a race to the finish!
