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.

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.
