A United Airlines Airbus A321neo entered a runway at Los Angeles International Airport (LAX) just as a United Boeing 787-9 was taking off, causing a near-miss incident. The A321neo had been instructed to hold short of the runway, but inexplicably crossed it anyway. Air traffic controllers quickly intervened to avert a potential disaster, but the 787-9 had to abort its takeoff, with its brakes overheating in the process. The 787-9 flight was delayed by around 8 hours as a result.

Why it matters

This incident highlights the critical importance of runway safety and situational awareness for pilots, especially at busy airports like LAX. A runway incursion of this nature could have had catastrophic consequences, underscoring the need for robust safety protocols and vigilance from both pilots and air traffic controllers.

The details

The A321neo was landing on runway 24R and had been instructed to hold short of the parallel runway 24L, which the 787-9 was cleared to take off from. However, the A321neo crew failed to hold short as directed and instead entered the active runway just as the 787-9 was accelerating for takeoff. Air traffic controllers quickly intervened, telling the A321neo to cross the runway without delay and ordering the 787-9 to abort its takeoff. The 787-9 reached a speed of 106 knots before its brakes overheated, forcing it to return to the gate with an 8-hour delay.

  • The incident occurred around 11:50 AM on Monday, March 2, 2026 at Los Angeles International Airport (LAX).
  • The 787-9 was scheduled to depart for Hong Kong at 11:10 AM but ended up taking off at 7:13 PM, an 8-hour delay.

The takeaway

This near-miss at LAX underscores the critical need for pilots and air traffic controllers to maintain the highest levels of situational awareness and adherence to safety protocols, even at the busiest airports. The quick actions of the controllers likely prevented a catastrophic collision, but the incident serves as a stark reminder of the risks involved in runway operations.
