New footage presents questions about potential reasons for the devastating aviation disaster in Washington yesterday. The clip shows the moment the American Airlines passenger plane was coming in to land at DC's Ronald Reagan Washington National Airport on Wednesday. Lights on both the doomed passenger plane and the Army Black Hawk helicopter were visible from more than a mile away. As both aircraft follow the fateful path towards each other, lights can be seen flashing on either aircraft before they collided, killing everyone in the air. Footage then shows the fireball erupting over the US capital before they came crashing down into the freezing depths of the Potomac River.

Officials are scrambling to learn the reason behind the tragedy, with many saying it could have been prevented. The clip raises questions as to why neither pilot was able to see the other in the clear night sky. Earlier today, police released names of all 40 victims whose whose bodies have been found so far following the devastating mid-air collision between a US Army helicopter and an American Airlines flight.

All 67 people involved in the tragedy - 64 on the airliner and three on an Army Black Hawk helicopter, are believed to have perished.

Ian Epstein was a flight attendant on the plane, his family said, adding that he was known for his ability to make people smile and was "full of life". "He loved being a flight attendant because he truly enjoyed traveling and meeting new people. But his true love was his family," the statement continued.

Danasia Elder was also working as a flight attendant onboard the flight, her family have told US media. Her brother-in-law Brandon Payne paid tribute to her, calling her "full of life".
