The recent crash of Air India Flight AI171, a Boeing 787-8 Dreamliner en route from Ahmedabad to London Gatwick, has brought into sharp focus the critical importance of reaction time for pilots during emergencies. The tragedy, which occurred shortly after takeoff from Sardar Vallabhbhai Patel International Airport, claimed the lives of 241 people, leaving only one survivor. Initial reports and expert analyses suggest the pilots had a severely limited window to respond to a sudden loss of power, possibly as little as 20 seconds, according to a former Air India 787 pilot.
The aircraft, carrying 242 people, including 230 passengers, two pilots, and 10 cabin crew members, crashed into a medical college hostel in the Meghani area of Ahmedabad on Thursday afternoon. The crash site was quickly swarmed by emergency services, including fire engines, ambulances, and police. The National Disaster Response Force (NDRF) deployed multiple teams to assist in rescue and recovery efforts.
According to available data, the aircraft lost power at a height of approximately 425 feet. Its vertical speed of descent was around 475 feet per minute. This rapid descent gave the pilots an extremely short time to react and attempt to regain control. Aviation experts have pointed out that the low altitude compounded the challenges, severely restricting maneuverability and further reducing the available reaction time.
The "Mayday" call from the Air India flight to Air Traffic Control (ATC) immediately after takeoff indicated the dire situation. The pilot, Captain Sumeet Sabharwal, a seasoned professional with over 8,000 hours of flying experience, reported a loss of thrust and inability to gain lift. Sadly, there was no further communication from the aircraft following the initial distress call.
Analysis of CCTV footage from Ahmedabad Airport reveals the flight was only airborne for approximately 32 seconds after takeoff. The entire sequence, from the start of the takeoff roll to the moment of impact, lasted less than a minute. This timeline underscores the incredibly compressed timeframe within which the pilots had to identify the problem, assess the situation, and execute corrective actions.
Several factors could have contributed to the crash, and the official investigation is underway, with experts from the U.S. and UK assisting Indian authorities. Preliminary considerations suggest a possible technical fault. The investigation will include a thorough examination of the aircraft's maintenance records, flight data recorders (black boxes), and other relevant evidence to determine the precise cause of the accident. The black box has been recovered which is expected to significantly aid the inquiry into the incident.
The tragedy has raised questions about the Boeing 787 Dreamliner, despite its previously unblemished safety record. The aircraft model has faced scrutiny over the years regarding potential safety concerns, and this crash is likely to intensify those concerns.
