On a wing and a prayer. When weather affects an airplane, it is one bumpy flight.  It's the first day on the job for flight attendant Michael Kruickshank and unfortunately his flight experiences three types of turbulence all at the same time; pilot, Laval St. Germain, must travel 500 precarious miles between low clouds and high trees - it's like flying through the eye of a needle; Flight attendant Fabrizio D'Amico suffers severe, unforeseen clear turbulence en route to Mexico, causing damage to the cabin and the passengers. Aviation instructors and weather experts explain the science behind how wind and atmospheric systems cause all forms of turbulence.
