On September 21, 1969, the Boeing 727-100 crashed during its final approach to Mexico City International Airport.

It was in the landing configuration; undercarriage down, flaps extended 30 degrees, leading-edge slats activated and stabilizer raised nose up by 10.25 units.

On its final approach, at 17:45, the three engines lost altitude and impacted the ground about 1,500 m (4,900 ft) from the runway threshold.

This caused the aircraft to become airborne until the landing gears and front body impacted a railroad embankment.

All three pilots and five flight attendants were killed; Captain Roberto Urías was reportedly still alive in the cockpit after the crash.

The crash site became a local interest point as many residents gathered to watch the ongoing rescue efforts from afar.
