Do more U.S. airports need control towers? That's one of the questions that has arisen following a midair collision at an airport in southern Arizona last week.

As investigations into the Arizona mid-air collision continue, debates over air traffic safety, regulation, and infrastructure modernization remain front and center.

As per the FAA’s most recent information, a troublingly large percentage of the nation’s air traffic control towers are understaffed, according to a report unearthed by Axios.

The Trump administration has defended its cuts at the Federal Aviation Administration by saying safety-critical employees weren't affected. Experts disagree.

Air traffic controller staffing has faced renewed attention after a January plane crash in Washington, D.C. Chicago has not been immune from challenges.

Tens of thousands of planes take off, land and perform touch-and-goes at the Marana Regional Airport in southern Arizona every year. Without an air traffic control tower, it's a calculated dance that requires communication by pilots.
