Any electrician knows you spilled water on wire, if the wire is wet, you ignore it, and there eventually will be fire. If 787 do have condensation issues it is a flying fire hazard, pure and simple. If 787 is prone to condensation like many of you have said, then it all makes sense. Nothing you can do on wiring, electrical systems, battery, will prevent a fire if there's condensation that make the electrical systems, wires, battery, wet over time, it will catch on fire.
I don't know what Boeing is doing to "fix" the condensation issue, but if it is not taken care of, 787 is a flying fire hazard waiting to happen.
