2HOOKS ON THE WINGS OF AIRPLANE
If you peek out the window to an Airbus plane’s wing, you can spot yellow bumps with holes in the middle on an otherwise smooth, white surface. If there’s an emergency water landing, the wings would be very slippery for passengers trying to get to the inflatable slide that would have deployed. To help travelers get off without falling, the easy-to-miss airplane features let cabin crew slip a rope through one hook and fasten it to the next, according to pilot ‘Captain’ Joe. Passengers could hold on to the rope while on the plane to make it away from the plane safely.
