The Black Hawk is a US Army workhorse helicopter. It has been flying for decades. One tragically collided with a passenger jet this week.

A day before the tragedy unfolded in the skies above the Potomac River in Washington D.C., another United States military helicopter reportedly came close to colliding with a passenger jet that had to abort its landing at the Ronald Reagan Washington National Airport due to a risk of a possible collision.
