A new technology for autonomously operating aircraft dubbed “MATRIX” is drawing scrutiny across social media after a commercial airliner collided with a military helicopter in Washington, D.C. on Wednesday.

The military helicopter that collided with a regional jet near Ronald Reagan Washington National Airport, in a crash that killed all 67 people aboard both aircraft, was a UH-60 Black Hawk, considered the “workhorse” of U.

A Black Hawk helicopter can transport up to "12 fully equipped, seated troops in combat," according to Lockheed Martin, the weapons company that builds the helicopter. There are about 5,000 of these helicopters in use by the United States Military.

The Army helicopter and regional American Airlines jet that collided over Washington are both workhorse aircraft that operate around the world on a daily basis.
