My own introduction: Good thoughts flow from this piece by Christine Negroni. It lays out a big picture of what Boeing and the investigators are grappling with and constructs those possibilities not included in press releases or news articles. I humbly recommend reading the complete feature as it may add to your own archival links of Boeing's journey to the flight of the 787.
****" Is it a coincidence that right after Boeing announced it had solved its first flammable battery problem it now may have another? It is worth considering if the Dreamliner's unique features have a role to play. Today Reuters reportedthat humidity and wiring are getting the attention of investigators in the U.K.. But I'm also pretty darn sure that the nature of the carbon fiber fuselage may also be under scrutiny."
