Imagine a really large lifting body, made of interlocked containers, building a honeycomb-like superstructure. Put some ablation layers around it. Maybe some small remote controlled rockets for steering. Let it glide down into the ocean near the coasts. Pull it into the the harbour via tug-boat. Remove remaining ablation layers. Disassemble honeycombed superstructure. Open containers. Get packets out. Melt containers into something else, or put them back up via space elevator, or whatever.
