Well, yes, it landed in the ocean by design and toppled over because that's what happens when you land a 50m tall spaceship vertically in water.

This sequence of events (even though expected!) reminds me a lot of the Monty Python and the Holy Grail speech:

> Listen, lad. I built this kingdom up from nothing. When I started here, all there was was swamp. Other kings said I was daft to build a castle on a swamp, but I built it all the same, just to show 'em. It sank into the swamp. So, I built a second one. That sank into the swamp. So, I built a third one. That burned down, fell over, then sank into the swamp, but the fourth one... stayed up! And that's what you're gonna get, lad: the strongest castle in these islands.

(although I suppose this ship fell over, then burned down, and then sank into the ocean)
