The plane was carrying 60 passengers and four crew members, while the helicopter had three soldiers on a training flight. It is believed that none survived the accident, which occurred on Wednesday night over the Potomac River.
The UH-60 'Black Hawk', manufactured by Sikorsky (a subsidiary of Lockheed Martin), is a twin-engine helicopter with four blades used in various branches of the U.S. Army. There are around 5,000 units in operation worldwide, with variants for the Navy, Air Force, and Coast Guard.
Since its debut in 1979, it has been involved in conflicts such as the wars in Afghanistan and Iraq, the invasion of Panama, and the operation that led to the killing of Osama bin Laden in 2011. It also inspired the movie 'Black Hawk Down'.
