Washington, D.C. officials have now positively identified 66 of the 67 people killed in Wednesday's midair collision between an American Airlines passenger jet and a military helicopter over the Potomac River.

U.S. Sens. Jerry Moran and Roger Marshall said Thursday afternoon that they have not been told who was on the flight from Wichita that crashed in DC.

An American Airlines regional passenger jet and a U.S. Army Black Hawk helicopter collided midair and crashed into the Potomac River near Reagan Washington National Airport on Wednesday night. Officials have not provided a death toll but said all passengers and crew on both flights were feared dead.

Officials confirmed Tuesday that all 67 victims in the DC midair crash have been recovered from the Potomac River, with 66 bodies positively identified.

Wind gusts and tidal conditions could slow operations today as officials try to pull wreckage from the icy Potomac River.

Data confirmed that the air traffic controller alerted the helicopter to the presence of the CRJ-700 about two minutes before the crash.
