There won't be salvage of the full structure. It's not a complete mystery. Recovery of the flight recorder and CVR will help solve whether it was simply a control problem or a structural failure, then presumably the useful parts in the investigation can be searched for. It's not a total mystery like the Comet crashes or the TWA 747, so painstaking (and very expensive) rebuilding is not necessary.
But please stop harping on about other unrelated incidents in this thread!
