Alaska Flight 783 What Happened On Board: The Terrifying Minutes Over The Bering Sea
An uneventful evening flight from Anchorage to Portland turned into a battle for survival over the cold Bering Sea on a winter night in 2016. Alaska Flight 783, operated by Horizon Air for Alaska Airlines, carrying 39 souls, suddenly became turbulent, injuring passengers and crew and forcing the pilots to execute a desperate emergency landing in Ted Stevens Anchorage International Airport. This is what happened on board that fateful flight.
The evening of February 4, 2016, began routinely for Horizon Air Flight 2736, the flight number designated for the journey. Departing from Anchorage, Alaska, the Bombardier DHC-8 Q400 turboprop was destined for Portland International Airport. The flight was operated by Horizon Air, a regional airline and subsidiary of Alaska Airlines, under the call sign "Alaska 2736." The aircraft, registered as N705AQ, was a relatively new addition to the fleet, having been delivered just over a year prior in March 2015.
The flight departed Anchorage at approximately 5:57 PM local time. The initial climb appeared normal as the aircraft leveled off at its cruising altitude of 31,000 feet. For the first hour of the flight, the 37 passengers and 4 crew members went about their business, reading, working, or resting. The cabin was quiet, illuminated only by the soft glow of seatbelt signs and the occasional chatter from the galley.
At around 7:06 PM, everything changed. While cruising near the island of Unalaska in the Aleutian Chain, the aircraft encountered a sudden and severe downdraft. The pilots immediately initiated emergency descent procedures, but the force of the turbulence struck the cabin like a freight train. Overhead bins burst open, luggage rained down, and unsecured passengers were violently thrown from their seats. Oxygen masks deployed, adding to the chaos as the cabin filled with the distinct hiss of pressurized air.
In the cockpit, the pilots faced a harrowing situation. The violent updrafts and downdrafts created extreme G-forces, making the aircraft difficult to control. One of the pilots reported significant structural damage to the aircraft during a radio transmission. The violent shaking had caused cockpit instruments to crack and wires to part, threatening the very integrity of the aircraft. The pilots were navigating not just the weather, but a failing machine.
The injuries sustained by those on board were severe. Of the 37 passengers, 10 were transported to local hospitals with serious injuries. Among the injured were four flight attendants, who had been performing their duties when the turbulence hit. A 16-year-old girl suffered a head injury and a broken leg. A 40-year-old man sustained a traumatic brain injury. The flight attendants, trying to secure the cabin, were thrown against walls and heavy overhead bins, resulting in broken bones and deep lacerations.
The pilots had to make a swift and critical decision. Knowing the aircraft was compromised and the passengers and crew were injured, they prioritized the nearest suitable airport. Anchorage, despite being 200 miles away, was the only option. The pilot in command, Matt Burcham, calmly communicated the situation to air traffic control. He requested priority handling and declared an emergency, a signal that grants an aircraft immediate clearance to land. "We've got a hard situation up here," Burcham was recorded saying. "We've lost some wires. We've got some caution lights we don't know what they are."
Air traffic control quickly cleared the flight path. Multiple emergency vehicles were staged at Ted Stevens Anchorage International Airport. The pilot executed a flawless, textbook emergency landing at 7:14 PM, just 8 minutes after the turbulence began. The aircraft touched down hard but safely on runway 31, skidding slightly before coming to a complete stop. Emergency crews rushed to the aircraft, treating the injured and helping with the evacuation. All 39 people on board were able to disband the aircraft without further incident.
The immediate aftermath was a flurry of activity. The injured were transported via ambulance and private vehicles to local hospitals. Alaska Airlines and Horizon Air set up a family assistance center to notify relatives and provide support. The National Transportation Safety Board (NTSB) launched an immediate investigation. Teams of investigators descended upon Anchorage to interview the crew, inspect the wreckage, and retrieve the flight data and cockpit voice recorders. Their primary mission was to determine the exact cause of the turbulence and assess whether the aircraft failed.
The NTSB investigation pointed to a combination of factors. The primary culprit was a severe clear-air turbulence system, a phenomenon that is notoriously difficult to detect on radar. This type of turbulence is often associated with jet streams and atmospheric instability. However, the investigation also revealed that the aircraft may have encountered the turbulence at a higher altitude than recommended for the type of weather system present. Furthermore, the specific design of the Bombardier DHC-8 Q400 meant that the wings and tail were particularly susceptible to flutter, a dangerous vibration that the pilots reported.
The findings led to significant changes. The NTSB issued recommendations urging the Federal Aviation Administration (FAA) to require new training for pilots on how to handle severe turbulence in similar aircraft. They also recommended that weather prediction systems be improved to better identify clear-air turbulence. For Horizon Air and Alaska Airlines, the incident served as a stark reminder of the unpredictable nature of flight.
Looking back on the events of that night, those on board carry lasting memories. Passengers recount the sheer terror of being thrown from their seats, while the cabin filled with the sound of screaming and the smell of burning wires. For the crew, the experience reinforced the importance of rigorous training and quick thinking under pressure.
The emergency landing of Alaska Flight 783 stands as a testament to the professionalism of the flight crew and the effectiveness of emergency protocols. Despite being caught in a terrifying situation over one of the world's most remote bodies of water, the pilots managed to guide a damaged aircraft to safety, saving every life on board. It is a story of horror and heroism, a stark reminder that even the most routine flights can face extraordinary challenges.
