It has been six weeks since 67 people died in a collision between an American Airlines flight and a U.S. Army Blackhawk helicopter in Washington, D.C.

Nearly two months after American Airlines flight 5342 collided with a helicopter, leading to 67 fatalities, the National Transportation Safety Board has provided an update on the investigation.

The agency says the approved helicopter route is too close to the approach to the runway where an American Eagle plane was attempting to land in January.
