On a snowy December morning in 1974, TWW Flight 514 was approaching Washington, D.C., with 85 passengers and a crew of seven on board. Unbeknownst to them, a small misunderstanding between the flight crew and air traffic control would soon escalate into a catastrophic accident that would change aviation safety protocols forever.
The Flight Crew
The flight was under the command of Captain Richard Brock, a seasoned pilot with 3,000 hours of experience on the Boeing 727. First Officer Leonard Kesik, with over 1,000 hours on the same aircraft, and Flight Engineer Thomas Safranek, a relatively less-experienced but capable crew member, were alongside him. Their combination of skill and experience seemed to ensure passenger safety.
Flight 514 took off from Columbus, Ohio, after completing pre-flight checks and ensuring passengers were securely buckled in. The Boeing 727, popular in the 1970s, was well-equipped for the short journey to Washington National Airport. However, as they climbed, unforeseen challenges awaited them.
Diverting to Dulles
Just 12 minutes into the flight, the trio received disastrous news: Washington National Airport had closed to arrivals due to high winds and inclement weather. Captain Brock was forced to divert to Dulles International Airport, which also faced weather challenges but was currently accepting inbound flights. This abrupt change added complexity to the situation, putting pressure on the flight crew.
As the crew prepared for their new destination, they quickly needed to familiarize themselves with Dulles's approach charts. This sudden shift in plans created a heavy cognitive load, making it difficult for the pilots to maintain their situational awareness while managing the flight. Despite their skills, the confusion was beginning to mount.
As the flight descended, the controllers issued a clearance to turn towards the airport—a shortcut that inadvertently led the crew off the expected approach path. While the pilots understood they were cleared to descend to 7,000 feet, they made a critical error when they assumed they were still under radar guidance. The reality was that the air traffic control was not monitoring their altitude, leading to a false sense of security among the crew.
In an environment of increasing doubt and confusion, the flight crew overlooked critical altitudes outlined in their charts—minimum safe altitude at 3,400 feet. However, with their focus on maintaining their clearance, they convinced themselves that descending to 1,800 feet during their approach was permissible. It wasn't until the radio altimeter alarmed that they realized their dire situation, descending rapidly toward the terrain.
Just moments later, as the aircraft hurtled toward Mount Weather at high speed, the pilots received an alarming warning that they were dangerously close to the ground. Despite desperately trying to regain aircraft control, the Boeing 727 collided with the mountain, resulting in a catastrophic impact and the loss of all lives on board.
Investigation and Industry Changes
In the wake of the tragedy, the National Transportation Safety Board (NTSB) launched one of the most consequential investigations in aviation history. This incident highlighted issues in communication between air traffic control and pilots, leading to significant changes within the industry.
Technological Improvements
Two major technological advancements were a direct result of Flight 514’s tragedy:
Ground Proximity Warning System (GPWS): This system alerts pilots when they are nearing terrain, greatly enhancing situational awareness and reducing the likelihood of controlled flight into terrain accidents.
Minimum Safe Altitude Alerts: Air traffic control systems were updated to provide alerts when any aircraft descended below the prescribed minimum safe altitudes.
Encouraging Open Reporting
Additionally, the establishment of a reporting system for pilots allowed for the reporting of incidents without fear of retaliation, aiming to improve overall safety culture in the aviation industry.
While the crash of TWW Flight 514 remains a tragic event, it spurred necessary advancements and changes in aviation safety, ensuring that such misunderstandings and mishaps become a rarity in the skies. From technology enhancements to clearer communication practices, the industry learned invaluable lessons from this incident, greatly enhancing the safety of all who travel by air today.
