Welcome to the NewsHour, the black box from the Army helicopter that collided with a passenger jet near Washington's Reagan National Airport this week has been recovered.

Investigators hope to gather valuable data as they try to understand what led to the deadly mid-air crash.

As John Yang reports, families were also briefed today by officials and met with the

medical examiner. Police boats were back on the Potomac River today as divers searched

for the remaining bodies of the 67 people who died in the mid-air collision of a passenger jet

and an army helicopter. Both aircrafts still submerged in the mid-air collision of a passenger jet and an army helicopter.

Both aircrafts still submerged in the icy waters.

And today, the first major change since the crash. The FAA shut down most low-altitude helicopter flights near the busy Washington-Ragan National Airport,

one of the nation's most congested air spaces, shared until now

by commercial jets and government helicopters. Meanwhile, NTSB investigators began analyzing

the passenger jets cockpit voice and flight data recorders, the so-called black boxes.

On Fox News this morning, Defense Secretary Pete Hegsett said the Pentagon is trying to find out

if the crew was using night vision goggles. If the qualification was a night flight, they could

have been used. You have a lot of ambient light, a lot of things happening around Reagan. There can be

depth perception problems. Again, that's speculation. Our investigation will tell us more.

Several news outlets say that at the time of the crash, one of the controllers in the airport's

tower was handling both planes and helicopters, tasks normally performed by two individuals.

That practice is allowed, but typically later in the evening when traffic is slower.

At the White House, reporters asked whether the flying public should be concerned about FAA

staffing levels.

In response, press secretary Caroline Levitt doubled down on President Trump's controversial

comments yesterday about diversity and inclusion.
