Here are 7 airport runway close calls just this year

Transportation Secretary Pete Buttigieg acknowledged on Wednesday that there has been an 'uptick in serious close calls' at U.S. airports.

There have been at least seven close calls this year confirmed by the FAA or the National Transportation Safety Board.

Buttigigieg said that the United States is on track to have more than 20 close calls in 2023.

A Republic Airways flight crossed a runway without clearance at D.C.'s Ronald Reagan Washington National Airport last week.
