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.

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

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.
