A Southwest Airlines flight bound for Dallas was forced to abort its takeoff at the San Antonio International Airport on Tuesday afternoon after air traffic controllers identified a runway conflict involving a small Pilatus PC-12 aircraft that had made a wrong turn and entered the runway assigned to the Southwest flight.

Why it matters

Runway incursions, where an aircraft, vehicle, or person enters a runway without authorization, pose serious risks to aviation safety. This incident highlights the importance of vigilant air traffic control and pilots' adherence to procedures to prevent potential collisions or other disasters on the tarmac.

The details

The Southwest Flight 4996 to Dallas Love Field was pulled off the runway around 1:40 p.m. after air traffic control canceled its takeoff clearance. The FAA said the action was taken because the single-engine Pilatus PC-12 turboprop aircraft, commonly used for business and charter flights, made a wrong turn and entered the runway assigned to the Southwest flight. No injuries were reported, and it was not immediately clear how many passengers were on board either aircraft.
