10. Ahmedabad Plane Crash: Air India AI171 London Flight Incident (2025)

A major aviation incident occurred when Air India Flight AI171, en route from Ahmedabad to London, faced an emergency shortly after takeoff from Sardar Vallabhbhai Patel International Airport. The aircraft, a Boeing 787 Dreamliner, reportedly experienced engine failure, forcing the pilots to make an emergency return to Ahmedabad. Approximately 270 passengers were killed in this accident.

How These Tragedies Made Flying Safer

Each disaster led to critical aviation safety improvements:
✔ Better cockpit communication (after Tenerife)
✔ Stricter maintenance checks (Japan Airlines 123)
✔ Advanced collision avoidance tech (Charkhi Dadri)
✔ Tougher anti-terror security (Air India 182, Pan Am 103)
✔ Improved aircraft design (DC-10 cargo doors, 737 MAX software)

Essential Questions About Aviation Safety

1. Could AI prevent future pilot errors?

2. Are modern planes truly safer than older models?

3. How do investigators determine crash causes years later?

4. What’s being done to prevent missile attacks on civilian flights?

5. Will supersonic air travel bring new safety risks?
