Prescott (whom I believe ended up with the card) eventually puts it into the slot by the door inside the airlock, and the door opens up.
[OOC] Let me know if you are closing the airlock doors behind you or leaving one or both of them opened.
Everyone trundles down the hallway, which is about 2.5 meters wide, and 3 meters tall. (about 8 feet wide, 10 feet tall). It is quite well lit, with white glowing panels in the ceiling, although occasionally there is one that is burnt out or dim. The floor is quite dusty, you can clearly see the footprints of where Zaras, the Medic and the robot were walking earlier.
After you have travelled about 300 meters, you can see that the corridor opens up into a wider area.
You are currently about 50 meters away from that area and can't see much into it yet.
