There you should be able to see the basic idea if you scroll down to the building ruins but I would love to see such things as ruined war ships and civilian ships to and old crashed planes, this would give Minecraft a more story driven feel because it already feels like a post apocalyptic world with villagers being the only people who survived along with the old temple and desert temple and stronghold ruins.
Space station crash.
Warship Wrecks / sunken Warships.
Air plane crashes / Helicopter crashes.
Vehicle Wrecks like cars and buses and maybe even trains.
I would love this as a mod but I cannot create this myself
