Nobody can hear a scream in the vacuum of space, or so they say.
No, wait – the exact phrasing on the Alien poster cheekily displayed in the Exobiology Lab was, “In space no one can hear you scream”. Which of course is highly contextual, since you obviously needed air to be able to scream, and anyone sharing your airspace would hear that scream. Then there were electronic communications systems. In this case, the communications system that had broadcast Hannah Sudha’s scream to the dozens of crewmembers in the Lander Command Module and hundreds more watching from the ship orbiting above. All of this tumbled through her mind in a wave of mortification.
