Delta jets collision incidents on the ground, while rare, do happen, and they’re always a cause for concern. On July 27, 2024, three Delta jets were involved in a ground collision at Salt Lake City Airport (SLC), highlighting a series of avoidable missteps that led to flight cancellations and significant delays. Here’s a closer look at what happened, why it occurred, and the implications for Delta and air travel safety.
What Happened During the Delta Jets Collision?
On the evening of July 27, 2024, three Delta aircraft were lined up for takeoff at SLC, waiting at the edge of runway 16L. The first in line was a Delta Airbus A220-100 operating flight DL1304 to Orange County (SNA). Behind it was a Delta Airbus A320 scheduled as flight DL2677 to Dallas (DFW). Lastly, a Delta Boeing 737-900ER, operating flight DL2046 to Bozeman (BZN), brought up the rear. Delta jets collision
The planes were facing a challenging tailwind, which is less than ideal for takeoff. Typically, planes take off into the wind to achieve better lift, but the wind direction was causing complications. The pilot of the first Delta jet needed extra time to calculate the takeoff performance under these conditions.
Meanwhile, the pilot of the third Delta jet saw an opportunity to expedite his departure. He communicated with the tower to request a takeoff from an intersection:
Unfortunately, this attempt to maneuver ahead did not go as planned. As the Boeing 737 made a right turn onto the taxiway to access the runway, its winglet collided with the tail of the Delta Airbus A320 in front of it. This Delta jets collision was immediately apparent and caused a flurry of activity to assess the damage and decide the next steps.
Immediate Aftermath of the Collision
Following the collision, it became clear that the incident had caused enough damage to cancel two of the Delta flights. The Airbus A320 and Boeing 737 had to return to the gate, and their passengers were left stranded, likely adding to the frustrations of those who had already been affected by Delta’s recent operational challenges.
The first Delta flight, which was dealing with its own issues related to the tailwind, faced further delays. The wind conditions worsened, necessitating a runway direction change, compounding the already complex situation. Delta jets collision
Analyzing the Delta Jets Collision: What Went Wrong?
Ground collisions involving aircraft are typically associated with pushback operations or maneuvering in tight apron areas. However, this Delta jets collision occurred under the control of experienced pilots on an open taxiway, making it particularly concerning. Here’s a breakdown of the factors that may have contributed to the incident:
Pilot Decision-Making: The pilot of the Boeing 737 made a judgment call to expedite departure, believing there was sufficient space to maneuver around the Airbus A320. This decision turned out to be incorrect, leading to the collision.
Air Traffic Control Coordination: The air traffic controller’s clearance was based on the pilot’s assurance that there was enough room to make the maneuver. This highlights the critical nature of accurate and cautious communication between pilots and controllers.
Environmental Conditions: The challenging tailwind situation added pressure to the decision-making process, as pilots were trying to optimize takeoff performance in less-than-ideal conditions.
Consequences and Lessons from the Delta Jets Collision
The immediate consequence of this Delta jets collision was the cancellation of two flights and the extended delay of a third. Passengers faced additional disruptions, which could tarnish Delta’s reputation, especially during a period already marked by operational challenges.
From a safety perspective, this incident underscores the importance of cautious and conservative decision-making. Pilots must always err on the side of safety, especially when there is any doubt about the feasibility of a maneuver. The air traffic controller’s role is also crucial in verifying and validating the information provided by pilots.
What Happens to Pilots After Such Incidents?
When pilots are involved in incidents like the Delta jets collision, several outcomes are possible, depending on the severity and circumstances:
Investigation and Review: The incident will be thoroughly investigated by aviation authorities and the airline to determine the root cause and contributing factors.
Training and Retraining: Pilots involved may be required to undergo additional training or simulator sessions to address the specific issues identified during the investigation.
Disciplinary Action: Depending on the findings, there could be disciplinary actions ranging from warnings to suspension or even termination in severe cases.
Operational Changes: The airline may implement changes in procedures or policies to prevent similar incidents in the future.
Improving Safety to Prevent Future Collisions
Preventing future ground collisions requires a multifaceted approach:
Enhanced Training: Regular and rigorous training for pilots and ground crew on situational awareness and decision-making in challenging conditions is essential.
Better Communication: Strengthening communication protocols between pilots and air traffic control can help prevent misunderstandings and misjudgments.
Technological Solutions: Implementing advanced ground surveillance systems can provide better real-time data to pilots and controllers, helping them make more informed decisions.
Proactive Safety Culture: Promoting a safety-first culture within airlines, where caution and conservatism are valued over speed and efficiency, can reduce the risk of such incidents.
The Bottom Line
The Delta jets collision at Salt Lake City Airport on July 27, 2024, serves as a stark reminder of the importance of cautious decision-making and robust communication in aviation. While ground collisions are not uncommon, they are typically avoidable with the right precautions and protocols in place. As Delta and the aviation community analyze this incident, the lessons learned will hopefully lead to improved safety measures and prevent similar occurrences in the future.
