CHICAGO — Pilots on a Southwest Airlines flight attempting to land at Chicago’s Midway International Airport were forced to climb back into the sky to avoid another aircraft crossing the runway on Tuesday morning.

An airport webcam video posted to X shows the Southwest plane approaching a runway just before 9 a.m. Tuesday before its nose abruptly pulls up. A smaller jet is seen crossing the runway that the passenger plane was set to use.

Southwest Flight 2504 safely landed “after the crew performed a precautionary go-around to avoid a possible conflict with another aircraft that entered the runway,” an airline spokesperson said in an email. “The crew followed safety procedures and the flight landed without incident.”

Audio recording of communication between the smaller jet and the control tower recorded its pilot misstating instructions from a ground tower employee, who repeated that the pilot should “hold short” of a runway. About 30 seconds later, the ground tower ordered the pilot “hold your position there.”
