One missed clearance. A tragedy that changed aviation safety forever. In dense fog at Tenerife, a KLM 747 began its takeoff roll while a Pan Am 747 was still on the runway. Overlapping radio calls masked part of Pan Am’s warning, and 583 people lost their lives. The key lesson: never begin takeoff without explicit clearance. What safety procedure do you think matters most?
