A blinding bright crescent appeared on the wall of the combustion chamber. Someone had opened the latch a crack. Silhouetted was the head of a person wearing some kind of getup that completely covered their head. They were breathing through a respirator. Visible just behind this person was a wall of plastic sheeting that had apparently been taped into place to create a barrier between the area surrounding the hatch and the rest of the mine shaft. They tossed a pair of bundles in and then closed the door.
