ASA Thunderstorms AND Airplane
Much research is done on the subject of thunderstorms, usually resulting in an admonition to stay out of storms. But staying out of trouble takes more than a resolve it takes savvy.
The pilot had extended the landing gear of the airplane, which is a good thing to do when turbulence becomes severe and control doubtful. If control of the airplane is lost with the gear down, the speed will build more slowly, allowing more time for recognition and correction of the situation
Weather forecasters often include the chance of thunderstorms to cover every eventuality not probability - which leaves pilots virtually on their own to decide whether or not thunderstorms will be a consideration along the flight path.
Richard Collins new edition of his book, Thunderstorms and Airplanes, provides in-depth understanding of why, when, and where the most lethal of weather hazards are likely to develop and gives practical advice on flying well clear of them. Chapters are dedicated to weather basics, thunderstorm research, storm forecasting, accidents related to thunderstorms, and more.
