It has been very nearly 3 months since the fire, so a lot of lost revenue and storage fees to top the final bill.
I would be interested to know how long it would take to repair a metal plane with similar damage levels as a comparison, but I understand that there are also concerns about toxicity during and after a composite fire like this one, so any necessary deep "clean-up" could also add to the bill.
I do have real concerns about the 787 and other composite airliners, and over other problems which have affected the 787. I also have great concerns about modern management attitudes and practices and how they seem to be compromising quality and reliability in a wide range of different industries as well as avaition.
The 787 does seem to have stumbled into several different areas of concern and I follow the unfolding saga with great interest and a certain amount of doubt. However, that does not make me a 787 hater.
