An American Airlines flight arriving at Ronald Reagan National Airport was forced to abandon 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.

An American Airlines plane arriving at Ronald Reagan Washington National Airport discontinued its landing, performing a go-around at an air traffic controller’s instruction to avoid getting too close to another aircraft departing from the same runway,

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.
