Air-safety officials are investigating a close call between a FedEx cargo plane and a Southwest Airlines passenger plane that occurred in Austin, Texas.

The incident happened on Sunday when the Southwest Airlines flight was preparing to land at Austin-Bergstrom International Airport. As the plane was descending, air traffic controllers noticed a FedEx cargo plane was on a collision course with the Southwest flight. The air traffic controllers quickly instructed the FedEx pilot to change course, and the two planes passed each other with only a few hundred feet of separation.

The Federal Aviation Administration (FAA) is now investigating the incident to determine what went wrong and why the two planes were so close to each other. The FAA has asked both FedEx and Southwest Airlines to provide any information related to the incident.

The incident has raised concerns among air safety officials about the safety of air travel. The close call between the two planes could have resulted in a catastrophic crash, and the FAA is determined to find out what happened and how to prevent similar incidents in the future.
