So you need to

How things actually work.

Cutaway from the video: How do you stop a fighter jet in 2 seconds?

You're coming in at over two hundred kilometers an hour, the deck is moving, and you have about a hundred meters to stop.

  1. So your jet carries a hook, and it snags one of the steel wires stretched across the deck.
  2. But stopping dead would be brutal.
  3. So the wire gives. Below deck, a piston pushes oil through a valve and soaks up the energy. The stop takes about two seconds.
  4. But what if your hook misses?
  5. So you go to full power the moment your wheels hit. Miss, and you fly off the end and go around.
  6. But from far out, how do you know you're on the right glide slope?
  7. So you keep the amber light, the meatball, level with the green ones.

Fly the ball, catch a wire, and two seconds later, you're parked in the middle of the ocean.

About

So You Need To… is a YouTube channel of short 3D explainers. Each video picks one problem, like stopping a river or landing a jet on a ship, and shows how it's done, with the machine cut open so you can see the parts that are normally hidden.

The facts in each script are checked before it's recorded. If you spot a mistake, leave a comment on the video.
