What are those hooks on the planes’ wings?
Don’t get too nervous, but those bumps contain holes on the wings that make it easier for flight attendants to attach ropes so they can deploy the inflatable slides in case of an emergency water landing. With them, you can hold the rope which will lead you to the inflatable slides and make it out safely, according to Captain Joe. Without the bumps, the wings would be too smooth and slippery for the passengers trying to get to the slide.
