That's right, Elizabeth, this has more carbon composites by weight than any other commercial jet so far. But not more than any aircraft--military planes have been successfully flying with very high proportions of carbon fiber composites for decades. In fact, that's where the technology got started.
I'm afraid all the issues surrounding the Boeing 787 make me skeptical about any plane that introduces new technologies. It seems that the 787 is again having difficulties, making two unscheduled landings this week.
This is great news, Ann, for the future use of composites in aircrafts. This craft uses the most composites so far, is that correct? I think this now shows proof that these lighter materials can work and sets the stage for a whole new phase in aircraft design and manufacturing. The fuel efficiency aspect is a real wiinner--have they said if this was achieved or not?
The Smart Emergency Response System capitalizes on the latest advancements in cyber-physical systems to connect autonomous aircraft and ground vehicles, rescue dogs, robots, and a high-performance computing mission control center into a realistic vision.
