Two planes almost crashed into each other Monday in Mexico City, an incident that comes after multiple aviation accidents in recent months have rattled travelers.

Delta Air Lines told The Hill’s sister network NewsNation that on one of its flights headed to Atlanta from Mexico City on Monday morning, flight crew onboard “observed another aircraft landing in front of their aircraft on the same runway” as the flight started to take off.

“Flight crew safely stopped their takeoff and returned to a gate,” Delta told NewsNation. “After taking on some additional fuel and conferring with Delta safety and flight operations officials, the aircraft redeparted for Atlanta at 9:42 am and arrived at 3:20 pm.”

In a Tuesday statement, Aeromexico said regarding “the event that occurred on July 21, on flight AM1631, operating the Aguascalientes – Mexico City route with an Embraer190 aircraft, we inform that we are working closely with the corresponding authorities to conduct a detailed investigation.”

“At Aeromexico, the safety of our customers and employees is, and will always be, our highest priority,” the airline added.

Airlive reported Tuesday that Aeromexico Connect Flight AM1631, early reports indicated, was about to touch down on a runway as the Delta flight had been cleared to enter the runway and start a takeoff roll.

The Federal Aviation Administration referred The Hill to “the Mexican authorities and Delta,” and the National Transportation Safety Board said it was “aware of the event but have nothing to release at this time.”

The Hill has reached out to transportation officials in Mexico for comment.
