Recent plane crashes, including the Air India disaster that killed more than 200 people in June, have led to increased scrutiny of air safety.

It's the second major near miss for Delta in the past week after an airline pilot took evasive action to avoid hitting a B-52 bomber over North Dakota.

An Aeromexico plane and a Delta plane just missed colliding at the Mexico City Airport in the early morning on Monday, July 21. According to AIRLIVE, Aeromexico Connect Flight AM1631 was trying to land at MEX from Aguascalientes when Delta Air Lines Flight DL590 tried to take off from the safe runway, heading for Atlanta.
