'All clear' at Reagan National Airport following unfounded bomb threat, Duffy says

Secretary of Transportation Sean Duffy says an "all clear" has been given at Reagan National Airport near Washington, D.C. on Tuesday following an unfounded bomb threat against a United Airlines plane.

"Earlier today, a United flight from Houston to Washington D.C. received a bomb threat. The flight landed safely at DCA, passengers were evacuated, and law enforcement conducted a full search of the aircraft," Duffy wrote on X. 

"The FAA has received the all clear and operations have resumed. I want to thank our brave men and women in law enforcement for their quick response," he added.

A ground stop was temporarily issued at the airport as passengers from the United Airlines flight were bussed to a terminal.

"The FAA is aware of a reported security issue on an aircraft at Reagan Washington National Airport (DCA)," the Federal Aviation Administration wrote on X. "Passengers have been removed, and the aircraft is away from the terminal while authorities investigate." 

"United Airlines Flight 512 landed at Reagan National Airport around 11:30 a.m. and then stopped on an adjacent runway away from the terminal in response to a security threat. Airport runways remained closed until passengers were safely offloaded and bused to the terminal," the Metropolitan Washington Airports Authority, which runs the airport, said on X. 

"Runways reopened at 12:50 p.m. Metropolitan Washington Airports Authority police are conducting a thorough investigation with the assistance of multiple law enforcement partners. Several flights were diverted to other airports during the runway closure," it continued.

"People meeting passengers or flying this afternoon should expect delays and check with their airline for updated flight information," it also said.
