Yesterday,An Air India Boeing 787 Dreamliner crashed almost 30 seconds after takeoff, killing 241 people on board (only one person survived). The Indian Home Minister said that the plane was almost fully loaded with 100 tons of fuel and exploded immediately after the crash. Since the crash site was a residential area, the accident also resulted in the death of more than 50 people on the ground.

India's aviation regulator said the plane sent out a distress call almost immediately after takeoff and then lost contact.

The pilot's last distress message was "no thrust, can't lift," which was consistent with the video that had been exposed. The sole survivor of the flight said he heard a loud noise as the plane struggled to climb.

So what exactly was the cause of this accident? Aviation experts speculate on several possibilities:

Dual engine failure (extremely rare):It may be related to fuel contamination and blockage, leading to fuel shortage and engine shutdown.

Bird Strike:Another possibility raised by some experts in India is a bird strike. Experts and pilots familiar with the Ahmedabad airport said it was "notorious for bird strikes", with a senior pilot saying bird strikes were rarely catastrophic unless both engines were affected.

Flaps not deployed:The video shows that the wing flaps do not appear to be set in the normal takeoff position. Flaps play a vital role during takeoff, helping the aircraft generate maximum lift at lower speeds.

The local temperature at the time of the incident was close to 40 degrees Celsius, which may result in insufficient lift under high temperature and high load conditions. However, there should be multiple checks and automatic warnings according to the procedure, so the probability of errors is low.

According to the New York Times, an Indian man who was said to have been on the Indian passenger plane two hours before it crashed shared a video,It means that there was an abnormal situation inside the aircraft at that time: the air conditioner, remote control, lights and call button all stopped working.

Airlines flying subsequent international flights without adequate maintenance may also cause critical systems to fail during takeoff.

Currently, Boeing and General Electric have sent personnel to assist in the investigation, and the specific reasons are still awaiting black box analysis.
