The tragic collision between a UH-60 Black Hawk helicopter and a Bombardier CRJ700 regional jet resulted in the loss of all personnel onboard, comprising 60 passengers and 4 crew members on the jet and 3 service members on the helicopter.

The passenger jet was manufactured by Quebec, Canada-based conglomerate Bombardier Inc. The CRJ program was sold in June 2020 to the Japanese company Mitsubishi Heavy Industries, which no longer makes them but continues to produce parts.
