An American Airlines flight was forced to abort its landing at Washington DC’s Ronald Reagan National Airport to avoid a plane taking off on the same runway — less than a month after a midair collision killed 67 people near the same airport.

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 a 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.
