Minecraft wiki entry for 0x10c, associated text: One specific great idea is opening the outer doors to put out fires. A stupidly dangerous move in interstellar space, sure, but very effective. Another thing I thought of is that doors need to be able to stop working, and then you need to be able to manually override them. Either by doing the clichéd blowtorch cutting thing, or by some hacking minigame. – Reddit, u/xNotch, September 15, 2012
