Interesting to think about. I know Starliner lands in Utah. I don't know where, but I'm guessing it's somewhere very remote. I wonder if the effort to get out to the ocean to recover a ship is significantly different than getting to a remote part of the desert to recover.
Additionally, I know when the first Crew Dragon landed, it clearly wasn't hard or expensive to get to given that there were a bunch of small, private boats that (inappropriately) approached the spacecraft. It was quite close to shore, not like the old Apollo missions landing in the middle of the Atlantic or Pacific.
