Note that the
Russians have *always* landed on land.

Except for the times they've hit a lake, at least twice, once with a
crew on board. At least that once didn't sink, unlike one of the
unmanned tests. Still, it was winter, and the combination of a
snowstorm restricting helicopter flights, ice making it hard to move the
spacecraft, and cold making for a dangerous night meant that the rescue
team was somewhat surprised to find the cosmonauts still alive when they
finally got the spacecraft to shore and the hatch open.
