The United States' streak of more than 15 years without a major fatal airline crash came to a shocking end this week.

An American Airlines jet carrying 60 passengers and four crew members collided Wednesday with an Army helicopter while coming in for a landing at Ronald Reagan National Airport near Washington, D.C. Here, we look at what happened and, more broadly, at aviation safety in the U.S.

It was expected to begin at 4 p.m. but has since then been rescheduled for 5:30 p.m. Once it begins, a streaming of the presser will be added to this story.

The midair collision at Reagan National Airport on Wednesday night has presented Sean Duffy with a major crisis just hours after he was sworn in as secretary of transportation.

CBS News confirmed only one air traffic control worker was managing the helicopters when the crash between a military helicopter and passenger plane occurred in Washington D.C. That is a job normally done by two people.

The National Transportation Safety Board did not specify how many air traffic controllers were working at the time of the collision.

The midair collision of an American Eagle-branded regional jet and a Sikorsky UH-60 helicopter near Washington, DC may be the first fatal crash involving a US airline since the 2009 crash of a Colgan Air-operated regional jet that killed 50 people.

Continental Airlines Flight 3407 crashed into a house in Clarence Center, killing everyone on board the plane.

Clues emerging from the moments before an Army helicopter collided with a passenger jet suggest breakdowns in the system meant to help aircraft land safely at the busy Reagan National Airport.

Facing his first crisis just two days into the job, Transportation Secretary Sean Duffy touted reforms sought by the president, who has lambasted DEI policies.

Wednesday’s fatal crash of a civilian plane and military helicopter at Reagan National Airport may reflect rising stresses on air-safety systems.

The last major collision of a commercial U.S. airline dates back to 2009, when a Colgan Air incident left 50 dead near Buffalo, New York. Federal regulators tightened safety requirements following the crash, including bolstering aircraft carrier inspection requirements and pilot training hours.
