The Army Black Hawk helicopter involved in the fatal midair collision in Washington, D.C., had a tracking system turned off, Sen. Ted Cruz said.

More than a week after the deadly collision of a passenger jet and a helicopter, crews forged ahead with salvage efforts in the Potomac River.

Data from air traffic control radar showed the military chopper was flying at 300 feet on the air traffic control display at the time of the fiery crash, according to the NTSB.
