I will ask you an extremely popular question in Poland: when do you think most of the plane crashes happen? Well, studies show, plane catastrophes are primarily during takeoff and landing. A lot of inexperienced passengers instinctively shows signs of stress and nervousness just in the initial and final phase of flight.
When the plane reaches a safe ceiling of approximately 10 thousand meters, the stress passes, you can unfasten the safety belts and the flight attendants begin serving food and drinks. Often, however, this idyllic atmosphere is disturbed by something we call turbulence.
