Family members of the victims of the plane crash in Washington, D.C., visited the crash site on Sunday morning. Dozens of the victims' loved ones could be seen gathered by the Potomac River to commemorate the 67 people killed in the deadly midair collision last week.

Officials say the conditions of the Potomac River are complicating recovery efforts of the bodies of the 67 presumed dead in a mid-air collision between American Airlines flight 5342 from Wichita and a military Black Hawk helicopter.

Officials said they do not believe there were any survivors and continue to investigate the cause of the collision.

I don’t know of any other accident that has had this amount of impact on aviation but also in other industries,” one expert said of the 1982 crash.

The plane crash that occurred over the Potomac River in Washington DC is learnt to have claimed several lives. There were 60 passengers and four crew members on the passenger jet that crashed, as per CBS.

The recent crash and rescue on the icy river between DC and Virginia sparks memories of Air Florida's 1982 disaster.
