The six debris investigation opportunities are pictured here. The first three, marked in red, are pieces of the wreckage itself, and are more difficult to reach. Numbers 4 through 6 are (theoretically, anyway) from inside the debris, and can be found at ground-level.

Volunteer below by commenting on any and all investigations you'd like your character to be in the running for! We'll RNG winners on the 15th, and the winners can choose any additional 'teammates' from there.
