Good point lomapaseo. A few pages back we heard some politician spouting off that he will have to be 1000% sure the 787 is safe before it goes back into service. It seems this has become a vague criteria for ungrounding. Everyone knows 1000% safe is imposible, however 100% safe is also not posible. Unfotunatly nothing is 100% safe. We can probably get to a point where it can be 99.999% safe but with all the hysteria I dont think any politician or FAA official will be brave enough to make that call. Some poor engineer low down in the chain will probably have to make that decision. Just like pilots become the scape goats for any SW assisted flying errors, engineers become the scape goats for any political/media assisted hardware issues .
From what I have read here about Li batteries there seems to be only 2 ways that would come close to meeting the ungrounding critera:
1. Fit a Ni Cad battery.
2. Provide a battery casing which will contain any fire that may happen to occur if the tripple redundant battery managment system fails.
