Despite several aviation disasters across the country in recent weeks and growing concerns about the safety of flying, an expert says air travelers have nothing to fear. 

The United States experienced three fatal plane crashes in just eight days, beginning with the deadliest aviation accident in America in the last 24 years.

Transportation Secretary Sean Duffy told Fox News last week that America’s skies remain the safest in the world but that many of the FAA’s systems remain “antiquated” and changes could be made to improve them.

“If it wasn’t safe, if there was an issue with air traffic controllers or staffing that couldn’t keep the system and the people safe in it, the FAA would shut it down,” he said. “We do have technologies on airplanes to keep them separated … our system does need to be upgraded.”

Boyd said that with more than half a billion people getting on airplanes every year, Americans should continue to “get on the airplane … go see grandma.”

“People should not be worried about flying,” he added. “It’s a whole lot safer than driving down the highway.”
