No equations, no math, no homework, no deep science—just common sense. There’s no technical background required or needed--only an interest in aviation safety and in why, on very rare occasions, bad things happen. We'll take several specific events, some well-known, some obscure, review what happened in each case, and then discuss WHY it happened. As a group we'll identify contributing causes and then, if possible, try to understand and articulate the ROOT CAUSE of each event. We'll also consider what has been done to prevent similar occurrences. Presentation will include PowerPoint and videos, and discussion will be encouraged. Lecture (plus questions). Facilitated Discussion. Viewing Videos.
