Investigators searching for wreckage from last week’s deadly midair collision between a US military Black Hawk helicopter and an American Airlines plane near Washington, DC, conducted an overnight scan of the Potomac River where the aircraft fell using advanced imaging technology to map the riverbed and locate debris.

More than a week after the horrific helicopter-plane collision near Washington, salvage crews have recovered most of the wreckage.

An attorney specializing in wrongful death and injury claims connected to aviation disasters says he is confident lawsuits will arise from the deadly plane-helicopter crash last week.

On Thursday, crews removed all large major components of the American Airlines jet and military Black Hawk helicopter, which collided in a deadly incident near Reagan National Airport last week.

All the major pieces of the wreckage of American Airlines Flight 5342 and the Black Hawk army helicopter that crashed over the Potomac River last week have been removed as of Thursday, according to military officials.

While on Capitol Hill on Thursday, the National Transportation Safety Board chair gave a brief update on the investigation into last week's deadly midair collision near Washington, D.C. CBS News senior transportation correspondent Kris Van Cleave has more on the recovery efforts.
