An experienced air traffic controller in Phoenix, Arizona, took decisive action to prevent a possible collision between two American Airlines flights late Thursday night. Both planes shared the same flight number and radio frequency, a situation that required immediate attention.

The incident involved American Airlines Flight 2482, arriving from Chicago at Phoenix Sky Harbor International Airport, and another plane departing for Chicago. The controller noticed these planes were on converging paths and quickly recognized the issue with their identical call signs.

To address the situation, the controller provided clear instructions by distinguishing the flights as “American 2842 departing” and “American 2482 arriving.” This action ensured the aircraft remained separate, allowing them to proceed without incident.

According to aircraft dispatch audio from ATC.com, the 25-year veteran shared with the pilots, “I’ve never seen two aircraft pretty much merge with the same call sign. That’s pretty incredible.” He also noted that while the outcome was positive, the situation had the potential to be disastrous.

The Federal Aviation Administration (FAA) confirmed that the planes maintained the necessary separation throughout the incident. The FAA is currently investigating the matter. American Airlines explained that the issue arose due to a delay at Chicago O’Hare International Airport. The arriving plane was supposed to land in Phoenix, pick up new passengers, and return to Chicago using the same call sign. With the delay, a different plane was arranged for the waiting passengers in Phoenix.

In an official statement, American Airlines expressed gratitude for the alertness and professionalism of both air traffic controllers and pilots. They stressed that “required separation was always maintained and the issue was identified and addressed.” Both flights continued without any further problems.
