Original Title: TIL that a loose checklist killed 11 soldiers. In 2015, a Greek F-16 crashed after takeoff, killing the crew and nine Frenchmen on the ground; 25 French, Italians, and Americans were injured. A checklist likely got jammed next to the yaw knob, causing the fighter to roll uncontrollably to the right.
