Not sure if this thought will answer your Q?
The famous Studebaker vehicle is a good example: when hit from different angles particularly front and back if it was metallic, the metal will shrug or show signs of fatigue; if it was fiber glass or composite material, it would break.
Based on the video provided on Japanese T.V it appears to me as if the fuselage would have broken in pieces leaving all passengers exposed to a more dramatic incident. However, the B787 has some strings interconnecting the fuselage parts attached, and it has a damper that makes passengers and crew ignore certain G's in-flight. Would this concept apply on the ground?? I am sure Boeing considered this possibility, they certainly made better landing gears on B747's compared to Airbus A380's, and more so, better and safer aircraft compared to English "aerocraft" manufacturers.
