Door Bomb and Safety Catches

Johnny leaves the airport by taxi, ending up in a disreputable part of town. During his ride we see another video phone call with a different interface, and the first brief appearance of some high tech binoculars. I’ll return to these later, for the moment skipping ahead to the last of the relatively simple and single-use physical gadgets.

Johnny finds the people he is supposed to meet in a deserted building but, as events are not proceeding as planned, he attaches another black box with glowing red status light to the outside of the door as he enters. Although it looks like the motion detector we saw earlier, this is a bomb.

This is indeed a very bad neighbourhood of Newark. Inside are the same Yakuza from Beijing, who plan to remove Johnny’s head. There is a brief fight, which ends when Johnny uses his watch to detonate the bomb. It isn’t clear whether he pushes or rotates some control, but it is a single quick action. Continue reading

Airport Security

After fleeing the Yakuza in the hotel, Johnny arrives in the Free City of Newark, and has to go through immigration control. This process appears to be entirely automated, starting with an electronic passport reader.

After that there is a security scanner, which is reminiscent of HAL from the film 2001: A Space Odyssey.

The green light runs over Johnny from top to bottom. Continue reading

Compartment 21

After the Communications Tower is knocked off, Barcalow, looking out the viewport, somehow knows exactly where the damage to the ship has occured. This is a little like Captain Edward Smith looking out over the bow of the RMS Titanic and smelling which compartment was ripped open by the iceburg, but we must accept the givens of the scene. Barcalow turns to Ibanez and tells her to “Close compartment 21!” She turns to her left, reaches out, and presses a green maintained-contact button labeled ENABLE. This button is right next to a similar-but-black button also labeled ENABLE. As she presses the button, a nearby green LED flashes for a total of 4 frames, or 0.16 second.

She looks up at some unseen interface, and, pleased with what she sees there, begins to relax, the crisis passed.

A weary analysis

Let’s presume he is looking at some useful but out-of-character-for-this-bridge display, and that it does help him identify that yes, out of all the compartments that might have been the one they heard damaged, it is the 21st that needs closing.

  1. Why does he have the information but she have the control? Time is wasted (and air—not to mention lives, people—is lost) in the time it takes him to instruct and her to react.
  2. How did she find the right button when it’s labeled exactly the same way as adjacent button? Did she have to memorize the positions of all of them? Or the color? (How many compartments and therefore colors would that mean she would need to memorize?) Wouldn’t a label reading, say, “21” have been more useful in this regard?
  3. What good does an LED do to flash so quickly? Certainly, she would want to know that the instruction was received, but it’s a very fast signal. It’s easy to miss. Shouldn’t it have stayed on to indicate not the moment of contact, but the state?
  4. Why was this a maintained-contact button? Those look very similar when pressed or depressed. A toggle switch would display its state immediately, and would permit flipping a lot of them quickly, in case a lot of compartments need sealing.
  5. Why is there some second place she must look to verify the results of her action, that is a completely separate place from Barcalow (remember he looks forward, she looks up). Sure, maybe redundancy. Sure, maybe he’s looking at data and she’s looking at video feeds, but wouldn’t it be better if they were looking at the same thing?

I know it’s a very quick interaction. And props to the scriptwriters for thinking about leaking air in space. But this entire interaction needs rethinking.
