The ISS is nearing its final years and this question spurred me to ask a follow up.
Let's say that the various countries grab whatever equipment/modules they provided in assembly and the ISS is geared to perform the retrograde burn and eventually splash down in the middle of the Atlantic Ocean. Is there (or would there be) a plan to disassemble the station to smaller "chunks" before reentry?
My armchair aeronautics engineering advice would be to disassemble the station and have several known entities reentering rather than deorbiting the whole station and have it break up into several unknown entities. Is that a reasonable/feasible plan or does it not really matter since the ocean is huge and all of the dangerously-moving debris will be confined to a safe area?
