The pilot has more than 500,000 TikTok followers and 700,000 Instagram followers under the handle @flywithgarrett.
He often uploads content about his travels and interesting facts about planes.
The most recent query from one of Garrett’s followers was what occurs when people use the lavatory on an aeroplane.
And it’s safe to say that his response has left people in awe.
On TikTok, Garrett captions his post: “Ever curious where it goes when you’re on the aeroplane?”
He explains in the video that many people believe that when a plane’s toilet is emptied midflight, human fluids just “dump out” of the aircraft.
As Garrett explains, this is undoubtedly not the case: “When you’re on an aeroplane and you have to 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.”
The clip has been viewed a staggering 4.3 million times and thousands have taken to the comments to share their thoughts.
Shocked, one viewer responds: “Since I was a kid I used to think when over a sea the pilot flushes it out. Omg!”
“Yeah! I had to ask a flight attendant. Was really interesting,” another adds.
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.
