The Federal Aviation Administration ordered a rare nationwide ground stop for all airports Friday -- a more than four-hour disruption that snarled travel from coast to coast with canceled flights and stranded passengers.
At a White House news conference Friday night, Transportation Secretary Sean Duffy blamed old technology that became overloaded and called on Congress to provide billions more in funding to modernize critical equipment, calling the situation an "emergency."
Department of Homeland Security Secretary Markwayne Mullin told reporters there was no indication the incident stemmed from a cyberattack, but that officials were still investigating.
Thousands of flights were canceled amid the ground stop.
"I believe that it's going to take us some time to get back to capacity," Duffy said when asked how long air travelers should expect delays and cancellations to continue.
Members of rock bands that were traveling to the Vans Warped Orlando concert helped to ease the stress and tension for passengers during flights Saturday.
Videos circulated online of Simple Plan, Hoobastank and The Used performing their hits using the plane's PA system to amused passengers.

Some of the passengers sang along to their songs.
"It felt like a tube of happy people," Hoobastank vocalist Doug Robb said in an interview with Rocksound Saturday.

Contractor releases statement on ground stop
Contractor L3Harris released a statement saying it takes the ground stop and its impact on travelers "seriously" after Transportation Secretary Sean Duffy said the company was updating communication infrastructure shortly before the ground stop.
"We are supporting the FAA in its investigation to understand the conditions that led to the Nov. 13 ground stop of our nation’s air travel. L3Harris takes the nationwide ground stop and its impact on travelers, airlines and air traffic operations seriously," L3Harris said in a statement.

"L3Harris has been modernizing the communication infrastructure supporting the National Airspace System in coordination with the FAA. With safety and reliability as our highest priorities, L3Harris, together with its telco partners and the FAA, has completed more than 70% of the planned airspace communications conversion from legacy copper wires to a fiber optic system," the company said.
Duffy said earlier that L3Harris was replacing copper equipment when a router started flooding other routers in the air traffic control system. This then caused instability that led officials to order a ground stop on Friday.
