Did you not read the post mentioning inbedded strain gauges?
Do you actually the think both Boeing and the airlines who have ordered the 787
are not aware of ramp rash and the possibility of unreported damage?
Do you know anything about the extensive use of composites in load bearing structure?
What do suppose happens on existing airplanes and rotorcraft when unreported damage occurs on composite structure? It's not exactly unheard of.
