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.

The Army Black Hawk helicopter that collided with an American Eagle flight over the Potomac River late last month was flying with a safety system turned off, Sen. Ted Cruz told reporters Thursday following a closed door briefing by the Federal Aviation Administration and National Transportation Safety Board.

In an update on Tuesday, officials say that transcriptions for both aircrafts cockpit voice recordings are ongoing.
