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

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.

What if all stars exploded simultaneously? Don’t expect it looking like fireworks because the consequences could kill you rapidly.

What if a gamma-ray burst hit Earth? The consequences would write off the planet at worst. But we may not exist without them.

What are aircraft? How many types there are? How they manage to design these mighty machines? And how air travel is the safest way to go?

What are chemical reactions? Why they are both essential and dangerous? And how you can perform different types of reactions?
