Finally, why is it taking Boeing and its insurers so long to even decide whether to repair or scrap since July if no safety of flight issue? We are coming up on two months with no actions
The fact that you don't know about it doesn't mean there is no "action".
Boeing stated long time ago that the jet will in fact be repaired but the method of repair will be a private matter between Boeing-insurer-Ethiopian. By the way I see zero evidence (based on aviation literature out there) that this event was "worse" because the fuselage was CFRP. You are entitled to your opinions of course. Ethiopian clearly doesn't share your bleak view of composite airframes - they laud 787's performance, efficiency and they want 8 more.
