> subsonic lift is well understood and has been for decades
I said easy. Not well understood. I can fly planes. It’s hard, and has limited room for fucking up. (It’s also hyperbole to suggest we understand lift. We don’t.)
Piloting a boat is easier and more forgiving. Hence, splashdown. You don’t need direction. You don’t need lift. Parachute physics is a backbreaker, but it’s symmetrical. Same for splash.
I love this comment. Thank you. For what it’s worth, I’m not a CFI but I did study actual astronautical engineering. Not much good once we’re in an atmosphere, which, granted, is where the boats and planes go. But I’ll stand by my statement that nobody—apart from interplanetary reëntry and drone teams—fundamentally understands lift. (I certainly didn’t when I was solving analytic solutions by hand.)

At no point were the astronauts piloting a boat. The reasons they splash down into the ocean has nothing to do with buoyancy being easier to solve, and even less to do with the ease of piloting a boat.

Maybe you personally do not understand lift, but "we" do in fact understand it. Please educate yourself before continuing this discussion any further.
