Air traffic control staffing was “not normal” at the time of a mid-air collision between a military helicopter and passenger plane in Washington, DC that killed 67 people, Transportation Secretary Sean Duffy has acknowledged.
US media reported that Reagan National Airport tower was understaffed during Wednesday’s crash, according to a government report.
One air traffic control worker was managing helicopters and some planes from the airport, a job normally done by two people, two sources told CBS News, the BBC’s US news partner.
