You’re hurdling toward the ground from thousands of feet up, and all you can think is, “So

All because I decided to take a little risk, live on the wild side!”

You, my daredevil friend, ignored that sign near the airplane toilet warning you to close

the lid before you press the flush button.

And it pulled you through and spit you out.

And, thus, we’ve come full circle: you’re freefalling to your untimely demise.

Wait, back up, you got pulled through the toilet?

As in, that tiny hole barely big enough for a mouse?

Ok, fine, exaggerated a bit on that one…

unless, you come out the other side all spaghettified?

The sound of knocking snaps you back to reality.

Uh-oh, you got lost in your thoughts again, staring down that waterless bowl and wondering

if the warning sign was put there to prevent the exact situation that just came flooding

You’re no fool – you know this plane is airtight!

Every crevice has been sealed to keep the cabin pressurized.

Because otherwise, none of us would be able to breathe this high up in such thin air.

(Must be a regular here on the Bright Side, I like it!)

And what about all those movies showing holes in the fuselage ripping passengers right out

When you flush the toilet, you open that hole, creating an opportunity for the pressure difference

Ok, let’s back up and tackle this thing one question at a time.

Even if you were somehow pulled through that tiny hole, you wouldn’t get spit out of

When you flush the toilet on an airliner, the contents don’t just get sprayed across

the Earth for everyone down below to, uh, have to deal with.

That would be gross, harmful for people and the planet…and illegal!

That umbrella wouldn’t do you much good either.

The stuff would be frozen from the cold temperatures at that high of an altitude.

Hey, that’s actually how planes used to do it in the olden days of aviation.

Hmm, pretty sure the stuff that we deposit into commodes shouldn’t be anywhere near

It’s not the waste itself but rather the liquid disinfectant that cleans the bowl with

That’s not to say airplanes don’t decorate the landscape with sewage these days…only

(It’s also incredibly rare, so no need to swear off ever leaving your house again.)

It happens if there’s a leak in the holding tank.

What’s been dubbed “blue ice” hailing down!

Sorry, pal, but the line’s growing out here!

But if you got pulled through the toilet, you wouldn’t end up hurdling toward the

ground – you’d just go to that onboard holding tank that keeps all the waste until

But what if the pilot accidentally empties it right there in the air?

OR what if he needs to, like to make the plane lighter in the case of low fuel or an emergency

Impossible – it can only be opened from the outside by ground crew.

They stick a giant hose to the bottom of the plane’s rear and pump the stuff out and

Hmm, makes me wonder: would you rather have a job like that and make all the money you

need, or the job of your dreams and barely have enough to get by?

If it goes to a tank, then what creates that incredible suction?

Well, the onboard lavatory system does make smart use of the pressure difference between

And that’s why it’s so loud when you flush.

It’s where that big blue sloshy mix of waste and disinfectant hang out.

It has a pipe that leads to a hole in the plane.

Don’t worry, it’s supposed to be there!

So, that means the pressure inside that tank is what it should be at 35,000 feet up.

But remember, when you do your business, the cabin has been pumped with a bunch of air

When you flush the toilet, it opens a sort of flap.

Because high pressure will always go where its lower when given the chance, the immense

air pressure in the cabin pushes whatever’s in the toilet down to the holding tank.

A lot of people waiting and worried out here.

If you don’t open the door soon, I’m going to have to open it myself.”

Just…having a bad reaction to the chicken!”

Even at breakneck speeds, the suction isn’t enough to pull you through.

It’s not even enough to push the compressed air out of the lavatory itself since there
