This idea wouldn’t actually solve most of the biggest problems during turbulence, which is people hitting their heads on the ceiling, and people getting hit by luggage falling out of the overhead storage.

I think having a cable flying around would actually be dangerous in itself. Wouldn’t want to get it caught around your neck…

It’s two cable lines, one on the ceiling and one on the floor. Each would be separately attached to the passengers harness so the freedom of movement is only up and down, limited to the amount of slack in the short length that connects the passenger to the plane.

We can give everyone a hard hat too.

You will at least not get sucked out when a door pops open again.

Not to mention the cables being a tripping hazard in the (far more common) ingress and egress situations.

I think you can forget about using the loo succesfully if you can't even walk down the aisle without incident...

This is a great point, I've often wondered why there are no seat belts on airplane toilets. Yes, there would be many obstacles to overcome (please, no course jokes) but there have been several times when I was using the facilities on a plane and turbulence ensued and I almost panicked thinking about all the possible bad things that could happen.

Now imagine your neck catching this zipline.
