Interlock
The outer doors slide open and I step in. Two sets of doors lead from the hanger to the magazine. A precaution that dates back to the days of iron ships that sailed on seas of water and men fought in the open air. Two doors prevents fire from flashing between compartments and accidentally setting off a catastrophic explosion. The mechanical interlocks prevent both doors from opening at the same time.
The outer door slides shut, cutting me off from the outside. The interlocks whirr and I hear a loud click as they unlock, I press the button again and the inner door slides up with a hiss of air. The magazine has been overpressured to keep stray sparks from floating in on the air.
Beyond is a cavernous bay, filled with racks of cylindrical objects. My mission is to destroy all these waiting messengers of death. But a single stray shot now, and they will take not only this ship, but me and my companions as well. I sling my gun and grasp my blade, and satchel.
