Visible crew/equipment: Watch the scene where Frank gets killed. In the last shot of this scene, we see a soldier standing over the dead body. Keep an eye on the right side of the screen as the camera slowly moves away and you should see one of the cameras and a cameraman on the ground next to a large metal object.
Answer: That question is actually answered. The pilot is speaking Finnish, and he says into the radio "lähetätkö helikopterin" which translates as "Can you please send a helicopter?" Looks like he was actually helping them after all, and there is still some civilization (or at least people with radios and helicopters).
