Families of victims of the deadliest US air disaster in nearly 25 years visited the crash site on Sunday just outside Washington DC.

Dozens of people walked along the banks of the Potomac River near Reagan National Airport, close to where an American Airlines plane and an army Black Hawk helicopter collided on Wednesday, killing all 67 aboard.
