Aviation safety expert says issue appears similar to September regional outage

Former United Airlines pilot and aviation expert Steve Arroyo said the problem appeared similar to a regional air traffic control communication outage in September that snarled hundreds of flights across the Northeast, except this time on a nationwide scale.

Arroyo said it could be linked to the outdated technology used by air traffic controllers.

“If you don’t have that ability, whether it’s because the old wires that they have are just run down or for whatever reason, you’ve got to stop airplanes on the ground,” said Arroyo. “And not put them in the air where you’re going to risk not being able to communicate with them.”
