I don't like your idea. Not. One. Bit. Unless you can pull it off of course, but that will be pretty hard.
I was experimenting with the ground level of Sandbox and the Crypt, and I thought, why not drop a mongoose from the ground level ceiling, into the Crypt? I was thinking about guiding the mongoose in with shield doors and grav lifts, and a funnel where the little hole thing that leads to the Crypt is, and it sounded like a good idea. I also experimented with the ceiling of the ground level, to the surface, but it wasn't a very satisfying fall. I'll see if I can work on it when I'm done with my ship map.
i already said that you'd blow up a few times. i do like your landing idea though it's better than mine because it covers more distance if you place a few of them.
