At what point is a restoration not a restoration? You're not really using anything original. You take a plane from the bottom of the sea, beat the barnicles off of it, disassemble it, and ... then what? You're not putting those pieces back together. Instead you are hand-tooling exact duplicates out of fresh metal. You put those new pieces together. The original plane is destroyed and the new creation takes its place. Rather like an old science fiction story about matter transportation. The original is used as a blueprint/template.
So what's really original about it? Not even some of the data plates are original. Most engines are not, or at the very least under go such rigorous rebuilds that half the parts are new and not original.
It's a loss to see such hardware broken in the dirt, I agree. Let's be honest though, it was the product of a lot of effort and a lot of specialized hand-crafting, but it was done in our lifetime. Most of it was newly manufactured. Even the recent Fw190 production reflects this. You can follow the blueprints exactly, you can make it to specs... But is it truly a restored plane? Or is it just a xerox? A copy? A nice copy, but a copy. Why not the next time a plane is "restored" create 2 new parts for every 1 part removed. 2 planes built out of 1 blueprint/example. All of a sudden you increase the reward for the same amount of original airframe lost. Soon you can make a production line and save some of those real WW2 wrecks for museums.
I'm of the mind to conclude the only possible explanation for the sentiments is: We get attached to the paint scheme, rather than the plane! That's got to be the reason! Or, maybe we get attached to the collective memory and perceived ties to the past, rather than the actual object that holds the memory?
Heavy stuff, indeed.
