We may get to the point where the airline cabin staff are wearing safety harnesses like ironworkers on a high rise building and they tie off onto a rail the runs the length of the cabin as they move the beverage cart down the aisle.
You’ll probably need some kind of track to secure the beverage cart, too.
It’s a little weird, but I always worried about that when I flew. I made sure I was sitting when the cart came down the aisle, as it sure seemed to me that if the plane banked or rose or dove suddenly, that cart could be lethally going down the aisle like a bowling ball, take out anybody in its path.
