Are Boeing's Battery Difficulties Part of a Much Bigger Problem?

In my opinion, I think Boeing has some more work to do. There’s two major issues I think they need to iron out right away. First, the lithium-ion battery, I think they are going to redesign, modify the design a little bit, to ensure that the fire would no longer be a threat. I think this one would push back for a few months at a minimum. The other issue they need to think carefully about is the composite material. This is the first time in commercial aviation history they use carbon fiber heavily on a commercial aircraft. The properties of all this carbon fiber up at 40 000 feet high is not very clear. Also, more importantly, the wings are developed by three different Japanese companies, and the wing is attached to the fuselage in the middle section of the plane using epoxy tape. Now, epoxy tape can sustain a certain turbulence, and also how it will work in the long haul, ...
