So Musk lays down his ideas for good battery design and is backed up by a guy from MIT. Seems fairly solid. Boeing guy says something like "I design battery cells not to fail, then assume they will. I then design battery so if one cell fails others won't. Then I assume they will and design for that." What we know is that the cells fail, then batteries fail, then noxious smoke blows into the cabin, so if what he says is true his designs have failed in three different ways. Seems to me Musk has more credibility here. Now, is this guy a clown? No -- he's probably a smart, competent guy who is doing what he's required to do given the situation he's in, while he's probably just been in ten meetings where people screamed "I told you so!" at each other.
