New footage has emerged showing the exact moment an American Airlines jet collided mid-air with a US military Black Hawk helicopter at Ronald Reagan Washington National Airport last year.Video shared by 60 Minutes captured the mid-air collision, with plumes of smoke rising and flames rising as the two planes collided with each other.The tragic crash that occurred on January 29 last year killed 67 people, including 64 passengers and crew on board the jet and three soldiers aboard the Black Hawk. The passenger jet, American Airlines Flight 5342, a Canadian-built Bombardier CRJ-701 twin-engine aircraft, was coming from Wichita, Kansas and was flying at about 140 mph over the Potomac River at an altitude of about 400 feet when the collision occurred.On the day of the collision, the Black Hawk helicopter, with call sign PAT25, was conducting a routine training mission through restricted airspace near the airport. Following the accident, the FAA implemented safety changes, including restricting helicopter traffic near the airport and moving some routes away from commercial flight paths. Transportation Secretary Sean Duffy said more than $12 billion has been secured to overhaul the air traffic control system. FAA Administrator Brian Bedford called the collision a “sober reminder” of the importance of safety improvements. The crash remains the deadliest mid-air collision in the United States since November 12, 2001.
