(is this ok?)
A crew member is crawling through the passageways on the crashed ship that arrived.
Crewman A: This is a bit cramped.
Crewman B: Keep going, there might be salvage!
Crewman A finds his way into the control room.
Crewman A: You were right. There's batteries, high-power computing equipment and a... steel tube...
Crewman B: Bring it out, we'll take a look.
Time passes.
The tube is placed in a hijacked MRI machine.
Scanner technician: Holy sh*t it's full of nanobots!
