U.S. Army Black Hawk helicopter collided with American Eagle Flight 5342 on final approach to Ronald Reagan Washington National Airport over the Potomac.

Data retrieved by the National Transportation Safety Board confirmed the Army Black Hawk helicopter that crashed into a passenger plane near D.C. was flying too high.

The flight traffic data NTSB has obtained confirms the helicopter was flying at 300 feet, the air traffic control display showed. That is 100 feet more than it should be flying in the
