An American Airlines flight arriving at Ronald Reagan National Airport was forced to abort its landing to avoid another aircraft Tuesday, officials said, 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 Federal Aviation Administration says an American Airlines plane arriving at Ronald Reagan Washington National Airport discontinued its landing, performing a go-around to avoid getting too close to another aircraft departing from the same runway.

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
