Air India Flight AI-2379 Altitude Drop Prompts AAIB Investigation
An airplane flying from Phuket to Delhi suddenly dropped about 300 feet in the sky.
That is like a very big bump while riding in a car.
The plane still landed safely in Delhi, but 17 people on board got hurt.
Now, special investigators called the AAIB are trying to find out what happened.
The two pilots have been asked to stay away from flying while the investigation goes on.
A health check on the captain needs another test, but no final answer is ready yet.
At first, the airline said the drop was probably caused by bad weather.
Later, some people thought there might have been a small problem with the plane's equipment.
Experts are also asking whether the crew reacted the right way.
We will have to wait for the investigation to know the real reason.
Air India flight AI-2379, flying from Phuket to Delhi, suddenly lost about 300 feet of altitude during cruise on August 4.
The Airbus A320 landed safely in Delhi, but 17 people, including passengers and cabin crew, were reported injured.
The Ministry of Civil Aviation has ordered the Aircraft Accident Investigation Bureau (AAIB) to investigate the incident.
Both pilots have been taken off flying duty pending the probe; the captain's routine psychoactive-substance screening reportedly requires confirmatory testing, with the final result still awaited.
The cause is under question, as Air India initially described a turbulence-related event while a later report cited a suspected transient technical fault.
