Failsafes

I looked over the containment complex arm of the space station through the viewscreen.

"So what if the containment fields fail?"

The technician brought up a display I only glanced at.

"The internal walls are 3 meters thick and made of diamondsteel."

"And if they fail?"

"We can blow the airlocks, and it'll empty the arm of air."

"And if that fails?"

"Then we blow the disengagement ring and detach the arm and allow it to burn up falling into the planet."

"And if that fails?"

"We blow up the station."

"And if that fails?"

"We end the timeline."

"... Good."
