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 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.

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

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

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.
