When you go to the toilet on the plane, will the poop fall directly from the sky ?

Rest assured! Absolutely, there must be a toilet on the plane. But it is not allowed to be used during take-off and landing.

The toilet will be turned off when the aircraft is about to take off and lift, when it is about to land and land, or when the air is turbulent, and the rest of the time can go to the toilet.

The J-10 is a light fighter, and the stay time in the air is three or four hours, and there is no problem of going to the toilet. Unless it is a long-distance flight after N in-flight refueling. In order to solve the problem of "convenience" for pilots, in the past it was to wear diapers. >>>More

On top of the plane there is a reservoir,Every time we go to the toilet, all these things are stored inside, and it is used to vacuum it to pump it out of the toilet, because there is a strong air pressure difference between the inside and outside of the plane Then, when they reach their destination, they will be all taken away and emptied by a fertilizer truck, instead of being thrown from a high altitude as some people think. >>>More

No, there are plastic bags underneath the toilets on airplanes, and toilets on trains are directly connected to the outside world.
