Imagine surviving a whole ass moon flight just to perish at sea because no one comes to get you..

I listened to Chris Hadfield describe coming home in a Soyuz capsul and it rolling a few times after hitting the ground. Land works but water sounds more comfortable, as long as you don't get sea sick on top of it all.

I have had the displeasure of knowing several people like this. In the post-truth landscape we find ourselves, there are really people out there who will call your denial of their alternative facts "unscientific" because they think that science is just about questioning everything, and they know their perspective is the right one.

Therefore, when their high school science teacher (who obviously hated them in particular for their good Christian beliefs) insists on ideas like the Earth being round, or the existence of climate change or—heavens forbid—evolution, she's obviously just trying to brainwash her students to believe her liberal agenda.

It's not just Americanas. Many prominent flat Earthers come out of England.

They did have to give them a special gun so they weren't killed by bears though.

I think she's saying 'pay attention' because she is used to people drifting off mid-sentence

Including the soyuz which to this day routinely lands on land

You are talking about surface tension. The importance parameter is speed not height and "like concrete" is a drastic simplification as both behave very differently on impact.

Notably whereas high divers have reached speeds of 60 mph the Artemis II splashed down at around 1/4 that speed a speed you too can obtain by jumping from about 10 feet up.

Speed, boats need to be outside the area where they might get hit, which is actually quite large.

Boats, even fast ones, are quite slow. And the larger boats that the fast ones would be deployed from are even slower. So even though that risk area gets smaller as the capsule descends, the big boats are waaaayy slower and still stuck far away. Generally, too far for 'fast' boats to get there quickly enough.

Helicopters are much faster, also relative to the size to be able to have medical staff on hand. So they can get there fast enough.

There is significant possibility of injury, and often times there are communication blackouts when they would already need to be leaving to make it in time. So, you send the fast thing.

Except when it exploded
