Well, flushing the toilet seems like a simple thing, but what if all people on Earth flushed simultaneously? The effects could be severe.

Last time, we’ve talked about the steps needed from the preparation to climb. Now we’ll tell you about the rest of the flight.

How to make a flight a success? Well, it is as complex as a spacecraft, and pilots need to deal with lots of complicated things.

What if there were no rain? Or what if there were no wind? Everybody knows don’t expect a better life, and it is certainly lethal.

What is sound? How to emit sound and why it appears? And why it can be both pleasant and deadly in different ranges?

What if we stopped reading? Don’t expect to play video games all day — it is much worse than you think.

What if we stopped exercising? Again, don’t expect your life to be easier. Without it, we wouldn’t be able to survive.

What if Sun changed its properties? Don’t expect a better life — one wrong parameter can lead to a mass extinction.

What if a black hole entered the Solar System? The consequences range from “nothing happens” to “Earth is doomed”.

What if a plane loses engines? Well, it’s not that serious. Pilots can often figure out an emergency landing before a crash.
