cabin pressure random situation: how do they react in a zombie invasion?

icarusing:

G-ERTI sits at her hanger, just having landed from a long flight from Finland. Her engines are powering down and tension hangs in the air.

Carolyn: “Don’t be ridiculous, Arthur, I don’t have time for your Wellsian attempts at sparking terror into all our oblivious and feeble hearts!”

Arthur: “No, but Mum, look at those people! It’s definitely exactly like how zombies act with the slow-walky bits and rotting flesh stuff. Eugh.”

Carolyn: “Arthur, enough, now please—”

Douglas: “Carolyn, you know how I hate to be the cloud on your sunshine-filled days, but might I remind you that we did have to land without any ATC clearance whatsoever, seeing as every channel we tried was completely silent.”

Martin: “Well with a piece of G-ERTI falling off every time we open a cupboard, I really don’t think—”

Douglas: “And the strange intermittent static from Stockholm until we cruised over the North Sea? I’m sorry Carolyn, but this is seeming rather suspicious and those scraggling groups of people do look rather…”

Carolyn: “Oh, don’t you dare say it!”

Douglas: “…zombie-y.”

Martin: “Douglas.”

Arthur: “Guys, listen! This is exactly what happens in that one movie with that guy in it who wakes up from a coma and everyone’s already zombies! We absolutely cannot go outside.”

Martin and Carolyn groan.

Carolyn: “Dear heart—”

Douglas: “Uh, Carolyn, I did just pull up the news on my phone.” (shows the crew the screen)

(moments of silence)

Arthur: “Well, since we might be here a while. Shall I put the kettle on?”
