An American Airlines flight arriving at Ronald Reagan National Airport was forced to abandon its landing to avoid another aircraft Tuesday, the New York Times reported, less than a month after a midair collision killed 67 people near the same airport and roughly 90 minutes before another close call between a passenger plane and a private jet in Chicago.

The near misses on Tuesday came after a string of aviation disasters, including the midair collision between an Army helicopter and a passenger jet last month that killed 67 people.

Pilots on a Southwest Airlines flight attempting to land at Chicago’s Midway Airport were forced to climb back into the sky to avoid another aircraft crossing the runway
