"But the problem with reincarnation is that it's hard to imagine what the storage medium for past lives would be. Not to mention the input-output device. I hesitate to rule it out completely, but I'd need pretty definite proof."
- Arthur C. Clarke

| Airlock | ||
| An intermediate chamber between airless space and the interior of a space craft. |
How can you go between the void of space and oxygen-rich interior of your space craft?
| DuQuesne reported briefly to the two girls. All three put on space-suits and crowded into the tiny airlock. The lock was pumped down. |

The phrase "air lock" and the basic purpose was first used in the mid-19th century in relation to sea-going vessels.
Not all airlocks and doors were tiny; this excerpt is from The Power Planet (1931) by Murray Leinster.
Those in the observatory felt a sudden savage suction
of air. It swayed them upon their feet.
“In a hurry,” said Jimmy Cardigan grimly. “The
Commander let in the air from the Planet instead of
the tanks. He’s in a hurry, too.”
This is perhaps the earliest usage of the phrase in science fiction. However, the idea was put forward much earlier; see the entry for the double-door vestibule from Astor's 1894 novel A Journey in Other Worlds.
Then there was the clank
of the airlock door — a vast circle a hundred feet across.
