When you board a plane, you know that you have to listen to a safety demonstration, which will help you in the unlikely event of an emergency while you’re onboard the aircraft.

It includes information on the brace position, oxygen masks that will come from the panel above your head in case of a drop in cabin pressure, and slides you may need to use in an emergency.

Of course, if you have any questions, flight attendants will be more than happy to impart their knowledge to you, as they have to undergo stringent training before they can work on the plane.

However, one six-year-old boy got more than he bargained for when he asked if he could go on the slide on the plane - probably thinking it was a fun playground ride, as opposed to a potentially life-saving device in the right circumstances.

Hannah Cantile shared a video of herself on TikTok, but you could hear the conversation between the child and the flight attendant.

The little boy said to his dad they were “going on the slide,” and he couldn’t contain his excitement.

The dad said, “No slide,” and the flight attendant echoed the father’s sentiment, sharing the boy wouldn’t be going on the slide.

The curious lad then asked: “What’s the slide for?” and the flight attendant said it’s used in “emergencies”.

He candidly continued: “So if everybody is about to die, that’s when the slide comes out."

Hannah uncomfortably laughed at how simply he put this, but many praised him for stopping the youngster from “asking any more unnecessary questions”. Someone also said kids don’t need “sugar coating and tiptoeing” and should be told the truth - even if it’s brutal.

The slide is deployed when passengers need to be evacuated quickly, such as in the case of a fire, smoke in the cabin, a water landing, or a crash landing. During a water landing, the slide may also double as a life raft for passengers.

It will automatically deploy if a cabin door is opened while the door is in the "armed" position. Doors are "armed" for slide deployment before takeoff and landing, so that in an emergency, the slide will inflate immediately when the door is opened.

The slide is not deployed during normal boarding or deplaning; in these cases, the doors are "disarmed" so the slide will not deploy.

Flight attendants are responsible for arming and disarming the doors and for initiating slide deployment in an emergency.

It is a critical safety device designed to help passengers exit the aircraft quickly and safely, and it is not generally used.
