When Vickers realizes Janek is really mutinying and going to ram the alien ship with the Prometheus, she has only 40 seconds to flee to an escape pod. She races to the escape room and slams her hand on a waist-high box mounted on the wall next to one of the pods. The clear, protective door over the pod lifts. She hurriedly dons her environment suit and throws herself into one of the coffin-shaped alcoves. She reaches to her right and on a pad we can’t see, she presses five buttons in sequence, shouting, “Come on!” The pod is sealed and shot away from the ship to land on the planet below.
The transparent cover gives a clear view into the pod. That’s great, since if there were multiple people trying to escape, it would be easier to target an empty one. The the shape inside is unmistakeable. That’s great because at a glance even an untrained passenger could figure out what this is. The bright orange stripes are appropriately intense and attention-getting as well.
Viewers might have questions about the placement of the back-lit button panels inside the pod, seeing as how they’re in a very awkward place for Vickers to see and operate. I presume she has some other interface facing her, and the panels we see in the scene are for operating when the pod is resting on the planet’s surface and its lid opened. From that position, these buttons make more sense.
I think that’s where the greatness ends. The main consideration for an escape pod is that it is used in dire emergencies. Fractions of a second might mean the difference between safety and disintegration, and so though the cinematic tension in the scene is built up by these designed-in delays, an ideal system shouldn’t work the same way. How could it be improved? There are three delays, and each of them could be improved or removed.
Delay 1: Opening a pod
Why should she have to open the pod with a button or handprint reader or whatever that thing is? The pods should be open at all times.
If pods had to be sealed for some biological or mechanical reason, then a pod should open up for her immediately when she enters the room. Simple motion detectors are all that is needed.
If she has to authorize for some dystopian, only-certain-people-can-be-saved corporate reason, then a voice print could work, allowing her to shout in the hallway as she runs for the pod.
Some passive recognition would be even better since it wouldn’t cost her even the time of shouting: Face-recognition or fast retinal scan through cameras mounted in the room or the pod. Run a quick laser line across her face and she’s authorized.
Delay 2: Suiting Up
Can she put on the environment suit in the pod? Yes, the pod is cramped, but that’s the biggest delay she experiences. Increase the size of the pod slightly to allow for that kind of maneuvering, and then she can just grab the suit as she’s running by and put it on in the pod’s relative safety.
Even cooler would be if the pod was the environment suit: All she would have to do is throw herself in the pod, activate it, and the minute she landed on LV223, the capsule transformed, Autobot-style, into an exosuit, giving her more protection and more enhancement for survival on an alien planet. Plus, you can imagine the awesomeness of letting Vickers fight the zombified Weyland Ripley-style.
Delay 3: Activation
This is one delay that I’m pretty sure can’t be either automatic or passive. The cost of making a mistake is too dire. Accidentally pressed a button? Sorry, you’re now being shot away from the mother ship faster than it can travel. Still, why does she have to hit a series of buttons here? Is it a (shudder) password, as a corporate cost-control measure? Yes, that spells dystopia, but it should be faster and more intuitive, and we’ve already authorized her, above.
Fortunately this doesn’t need much rethinking. Since we’ve already seen a great interaction used for an emergency procedure, i.e. the 5-finger touch-twist used for emergency decontamination on the MedPod, I’d suggest using that. Crew would only have to be trained once.
The total interaction, then, should be that Vickers:
- Runs to the escape room
- Is identified passively (and notified of it by voice)
- Grabs a suit (this is optional if you go with the awesome exosuit idea)
- Throws herself into an open pod
- Performs a simple gesture on a touch pad
- Is shot away from the soon-to-explode ship
Bam! You have saved massive amounts of time, a crewmember removed from the immediate danger, and you have the setup for an awesome ending where Vickers in her exosuit can just punch the falling alien spaceship out of the the way rather than running from it like a moron.

One other option for activating the pod would be to require a two-hand gesture, such as pressing at the same time two buttons that are far enough from each other. This pattern can be seen occasionally on dangerous machinery. Of course, if you happen to have lost a limb, you are out of luck.

May be the pod is not exclusively an espace pod, but may be a contamination or decompression safe-area : You may have to go in a pressured safe for some minutes or hours due to a depressurization, or any lethal chemical leak, but not leaving immediatly the ship.
As we have massive amount of propolent, chemical products for purification or what you can imagine, may be those pods may have numerous safety functions, as they have their very own energy source.
I would have to design any hazardous factory in space, it makes sense
Entirely possible! Though keep in mind that while backworlding like this can help us make sense of an interface in the diegesis, for design practice we would want to focus on what we can improve.
After posting this, I remebered that only a small part of the living space of the ISS is enough shielded in case of solar or cosmic radiation deadlty peak. So this emergy pod may be also act as a temporary shelter in case of deadly radiation. Exiting the ship would be counter-productive.
On the suit-up first phase, my theory is that they may be an inflatable pillow, as a kind of airbag, to lock firmly but gently the body during ejection. (I’ve seen this movie a very long time ago, but this theory is may be wrond because of screens at the upper part, and because nothing seems here to avoid the neck to break).
So it may need a small volume to inflate, both for speed and also to keep the fabric solidity. And also to have a restricted and previsible position for the body of the operator.
But you’re losing time, and yes, having a full pressured espace pod would be so easier.
