The shallow trench carved out by the crashed shuttle seemed a convenient enough path to the perimeter wall. Judging by the occasional blast crater in the side of the trench, the shuttle had already taken out any mines along the way. Or so you hoped.
You didn't step on any approaching the shuttle, at least, so that part was a success. Approaching the shuttle, you could see that, at least from outside, it was mostly intact, not counting heavy damage to a wing - one maneuvering flap was entirely gone. By the look of things, its impact with the wall had crushed the pilot's cabin as well, but at least the wall was a bit worse for the wear as well. Instead of a steep, smooth surface, it was now missing a good-sized chunk and had quite a few cracks running up the damaged segment. It was still some 12 metres tall, but at least with all the damage, it should be possible to climb it.
As for the shuttle's rear hatch, it was still closed, though the panel on the side still seemed to have power.
