WN1478 - Incident: Southwest B738 at San Diego on Oct 11th 2024

A Southwest Airlines Boeing 737-800, registration N8551Q performing flight WN-1478 from San Diego,CA to Dallas Love,TX (USA), was cleared to line up runway 27 for takeoff and hold.

A Southwest Airlines Boeing 737-700, registration N262WN performing flight WN-785 from San Diego,CA to Phoenix,AZ (USA), was taxiing for departure and due to closure of taxiway B between B4 and B6 for work in progress needed to cross the runway at B6 to reach the holding point via taxiway C. Ground Control cleared the aircraft to cross the runway while WN-1478 was aligning with the runway.

Shortly afterwards WN-1478 was cleared for takeoff, WN-785 was just about to cross the hold short line. A few seconds tower can be heard "Southwest 1478, Cancel Takeoff Clearance" and ground can be heard "Southwest 785, hold position", the crew reported they had already crossed the hold short line.

WN-1478 did not react to the cancel takeoff clearance instruction, tower repeated the instruction, only then the crew acknowleged "rejecting". The aircraft rejected takeoff at about 100 knots over ground and slowed reaching taxispeed before reaching B6, then turned via taxiway C6 onto taxiway C. WN-785 was then cleared to cross the runway onto taxiway C, too.

However, N8551Q subsequently needed to return to the apron for checks but was able to depart with a delay of about 3 hours, WN-785 departed about 20 minutes later.
