A quick-thinking Phoenix air traffic controller calmly averted disaster after two American Airlines planes with the same callsign accidentally ended up on the same radio frequency while flying directly toward each other.
The bizarre mix-up happened shortly after midnight on Friday, August 14, when one aircraft flew in from Chicago while another had just departed Phoenix. Both were heading toward the same area as they communicated with air traffic control, creating a potentially dangerous communication problem for the controller handling them. Normally the same plane flies both legs of the round trip, but American employed a second aircraft after the flight out of Chicago was delayed by bad weather. Both were still assigned the number American 2482.
Newly released audio posted by ATC.com reveals how the potentially dangerous encounter unfolded. The controller can be heard addressing “American 2482,” initially asking the arriving aircraft to maintain an altitude of 10,000 feet. He then realizes there is another American 2482 in the area, this time a departing flight, and quickly tells the second aircraft to maintain 9,000 feet.
“Traffic one o’clock in 10 miles. Is your company, same callsign,” the controller tells the departing pilot, alerting them that another American Airlines aircraft is nearby.
Moments later, the situation becomes even more tense as the controller warns: “Traffic 12 o’clock in three miles is your company.”
The departing pilot confirms they can see the other aircraft, while the arriving flight also reports having the other American 2482 in sight. The controller then manages to separate the two aircraft by keeping them at different altitudes before allowing the flights to continue on their respective routes. He quickly started referring to “American 2482 on the arrival” and “American 2482 on the departure” to keep the two planes straight, making sure the pilots of both airlines saw each other when they were still miles apart.
Once the immediate danger had passed, the controller admitted just how unusual the situation had been. “I’ve been working air traffic for 25 years. I’ve never seen two aircraft pretty much merge with the same callsign,” he said. “That’s pretty incredible.”
The pilot added: “Same frequency and pointing right at each other. That’s pretty crazy.”
The controller agreed: “It could have been disastrous, but I’m glad it all worked out.”
Speaking to the Associated Press, aviation safety expert Steve Arroyo said the airline failed to realize that two planes with the same flight number would be in the air at the same time. “You can drop the ball and that shouldn’t happen, but it’s nice to see that the system is resilient and we have all the safeguards,” he said.
In the viral moment that drew widespread attention to air traffic control procedures, the incident highlighted how a single operational oversight — assigning identical callsigns to two simultaneously airborne aircraft — could create confusion where pilots might misinterpret instructions meant for the other plane. If both pilots had thought the controller was telling them to fly at the same altitude as they headed toward each other, they might have collided, making it crucial they knew which plane he was directing. The controller’s quick thinking to distinguish the two flights by their arrival and departure status, combined with maintaining vertical separation, prevented a potential midair disaster.
Launching an investigation into the matter, American Airlines wrote: “The diligence and professionalism of air traffic controllers and our pilots ensured required separation was always maintained and the issue was identified and addressed. Both flights continued safely and without incident.”
The Federal Aviation Administration is expected to review the incident as part of ongoing safety oversight.
