"I would just say that everyone who flies in American skies expects that we fly safely," Duffy said. "That when you depart an airport, you get to your destination. That didn't happen last night and I know that President Trump, his administration, the FAA, the DOT, we will not rest until we have answers for the families and for the flying public. You should be assured that when you fly, you're safe."
Reagan Airport will reopen at 11 a.m. Thursday, the Federal Aviation Administration announced. The FAA previously said it would be closed until 5 a.m. Friday.
Duffy, just sworn in earlier this week, was asked if he could reassure Americans that the United States still has the safest airspace in the world.
