It's hard to say from a glance at the bottom of the fuselage. There are intact seats that might have goodies hidden under them, closed overhead compartments that could still be full, and the partially-crushed cargo section is pretty dark, so almost anything could be lurking in there. Squalo might be able to get away with prying off some ceiling panels or digging into the crushed sections in the walls and floor to hunt for salvageable electronics, but that will take dedicated effort - effort that would have him hanging inside an incredibly precarious airplane wreck, for not-guaranteed loot.

Day 004
Hour 4: VI.Z.29 -> VI.AA.29 (chunk of basalt)

Squalo hits the end of a valley at this point, forcing him back into more mountainous terrain unless he wants to do a lot of backtracking. He can see a definite mountain peak to the southeast - by far the tallest, most well-defined one he's seen in the region. It has a rim to it that suggests a caldera.

Hour 5: VI.AA.29 -> VI.BB.29 (five olives)
Hour 6: VI.BB.29 -> VI.CC.29
Hour 7: VI.CC.29 -> VI.DD.29
Hour 8: VI.DD.29 -> VI.EE.29

From his position near the peak of the central mountain, Squalo can see the start of another mountain valley to the northeast, and specifically, what might be the roof of a small building nestled in it.

Squalo has an easier time finding a sheltered set of rocks to camp in tonight; trees are kind of sparse around here.

It's now the start of Night 004.
