Turbulence is mostly not dangerous and will not in most flights cause the plane to crash or fall out of the sky from the Turbulence.
Turbulence can cause a plane to crash but it's very rare that it does as you have a very experienced pilot at least when flying in a commercial aircraft.
The pilot knows how to handle the aircraft when they experience Turbulence so as long as the plane is in good working order which it should be then you should not have to worry about a plane crash because of the Turbulence.
A very experienced pilot is never scared of turbulence because they have learned through several flights that turbulence is not dangerous and Turbulence will not cause the plane to crash even though it feels like it to the passengers.
It's mostly passengers that get scared of Turbulence when it happens and you might think that the plane is gonna crash and you're gonna die but it's nothing to worry about.
I've flown on several commercial airplanes and experienced Turbulence almost all of those times and at first I was scared of it but after the second and third flight with turbulence I stopped being scared of it.
So a good pilot and most pilots are not scared of the Turbulence.
