In Star Trek, whenever a ship is hit with something — whether it be weapons, an energy wave, or some large and massive object — it shakes. Sometimes, the crew is just rocked back and forth on their feet (or in their seats if they're on the bridge — the stabilized GIFs look hilarious!). However, the motion is sometimes powerful enough to throw the crew off their feet and out of their seats in a dramatic and unnatural fashion (at least Discovery makes it look believable and painful).
We know from earthquakes that horizontal motion in the ground makes it really hard to stand up straight, let alone walk or run properly. It could be easy to lose your balance on a starship when it is hit by something.
But when a ship is under attack, and dozens of people are sprinting through any given corridor segment under low-light red-alert conditions, someone is bound to lose their balance and slam sideways or even face-first into a wall or the floor. Anyone could be seriously injured.
And yet, I've never seen any safety features in the corridors. No handles, no soft and shock-absorbing padding of any kind, no fold-down seats with seatbelts, no straps to hold on to. When something big is coming and a massive impact is imminent, someone on the bridge often declares to the crew, "Brace for impact!" What will everybody on the lower decks (wink wink) do?
Am I missing something? Have I just not seen some hidden safety features? Or are they truly missing from ships? Why haven't I seen them before?
