Exactly, a stupid article to start with
A 787 has how many parts? How many systems? So a battery is showing signs of trouble, on what is a new model. You fix it and move on.
I went on the tour of their factory in Everett WA. Amazing facility. The 787s come in one side in sections. I think the entire fuselage is about 6 sections that they basically glue together. The parts come in one side and the entire assembly moves continuously until its complete and roles out the other side ready for paint. They could probably store a few hundred 787s while the battery problem gets worked out. Not that it will take that long.
Imagine a room so big that a 787 looks small. The room for the 747 is even bigger.
