An airline pilot has gone viral after revealing where everything goes after you flush the toilet on a plane. 

The pilot, who goes by the username @flywithgarrett, has 700,000 Instagram followers and over 500,000 TikTok followers.

He often uploads content about his travels and interesting facts about planes.

Garrett also answers his followers’ questions, with the latest being about what happens when passengers use the aeroplane toilet.

And it’s fair to say his answer has left people gobsmacked.

Watch this man get revenge on a fellow plane passenger who kept opening his window shade…

On TikTok, Garrett captions his post: “Ever curious where it goes when you’re on the aeroplane?”

In the video, he explains that a lot of people are under the presumption that bodily fluids simply get ‘dumped out’ of a plane when a toilet is flushed midflight.

This is definitely not the case, as Garrett says: “When you’re on an aeroplane and you gotta go, where does it go?

“Did you know that whenever you flush the toilet on the aircraft, it actually doesn’t dump out into the population down below?

“It goes through plumbing to the rear of the aircraft and the seal compartments where the ground crew at the destination will remove all that waste.

“On a 747 – on a long haul flight – toilets can be flushed over a thousand times, creating over 320 gallons of waste.”

He adds: “That’s a lot.”

Tagging a friend, a third person says: “See, I told you they didn’t dump out.”

“I thought they dropped it in the ocean,” a fourth admits.

While another says: “I just haven’t thought about this like ever.”

Many others have taken to the comments to say they can’t believe people ever thought otherwise.

One TikToker questions: “Other actual people believe that it would get expelled from the aircraft to the population below? And if so, do these people vote?”

Another asks: “Wait… people actually think it dumps out below?

“So they think there’s poo falling out of the sky and it’s not the birds?”

“I still don’t get it that there are still people that believe aeroplanes just dump it,” a third viewer remarks.
