The Deadly Crashes That Led to Safety Improvements in Air Travel

🔍Investigators discovered a problem with the Twin Otter plane's tail movement during Flight 1121. This led to the suspicion of a stall caused by the early retraction of the droop lever.

🚁The crash of Flight 548 was caused by confusion over control levers. The pilots mistakenly retracted the droops instead of the flaps, leading to a dangerous stall.

📡The collision between Flight 706 and an F-4 fighter jet highlighted the lack of communication between military and civilian systems. Changes were made to prevent similar accidents.

🔧Cockpit design and instrument monitoring played a role in both crashes. The complexity of cockpit design and the introduction of new systems can create challenges for pilots.

🌐The crashes led to significant safety improvements, including changes in cockpit design, communication systems, restricted airspace regulations, and pilot training.
