Just one caveat on that: turbulence is very common and not dangerous at all to the aircraft or to anybody onboard who is strapped in.

Severe turbulence is extremely dangerous to unsecured people on an airplane. And the severe variety isn't as unlikely as most people think. The NTSB of the USA publishes monthly accident reports online, and it's a rare month where one or more flight attendants and/or passengers on a commercial airplane aren't injured during a turbulence event.
