The National Transportation Safety Board (NTSB) is sending a team to investigate a loss of separation event that occurred on October 29 between a Southwest Airlines Boeing 737 and a Eurocopter helicopter, the agency announced on Friday.

The close call took place near Cleveland Hopkins International (CLE) Airport in Ohio as Southwest Flight 1333 was making its final approach on a flight from Baltimore-Washington International Thurgood Marshall Airport (BWI), according to news reports.

The helicopter in question was an Airbus H145 belonging to a medical services company that was en route to pick up a patient in Cleveland at the time of the near miss.

As a result, the Southwest flight had to abort their initial landing, but was able to land a short time after.

Data from Flightradar24 shows both aircraft at the same altitude as the medical transport helicopter passing in front of the Southwest flight, with just 0.56 miles of lateral distance separating the two.
