The National Transportation Safety Board (NTSB) on Tuesday issued two “urgent” safety recommendations after discovering thousands of close calls between helicopters and planes near Ronald Reagan Washington National Airport following a midair collision in January.

A medical transport helicopter crashed Monday in Mississippi, while carrying two hospital workers and a pilot, officials said.

A University of Mississippi Medical Center medical transport helicopter crashed into a wooded area in Madison County on Monday.

Three people aboard a medical helicopter were killed when the aircraft crashed in rural Mississippi, officials said.

An American Airlines passenger jet and an Army helicopter collided on Jan. 29 as the plane prepared to land at Washington, D.C.’s Ronald Reagan National Airport.

Transportation Secretary Sean Duffy said the National Transportation Safety Board’s recommendations will be accepted.

The NTSB is calling for a strict ban on helicopter flights near Reagan National Airport after a deadly midair collision killed 67 people. Chair Jennifer Homendy urged the FAA to act immediately, citing an "intolerable risk" of collisions.
