TURBULENCE and AIR POCKETS
Hi everyone, i am not a pilot but i am about to start flying lessons. I fly several times a year and i am scared of turbulence. I find i get very tense and i also panic if the plane hits an air pocket, its the fact it literally drops down in the sky.... how much turbulence can a 777 or 737 take before it becomes a danger and the possibility of a crash? I flew on a houston gatwick flight recently and it was big bumps the whole time nearly but we didnt change altitude and i became very distressed..... is it dangerous,, shouldnt we have changed altitude??? can anyone explain this?
