Newly released data from ground-based radar came out Tuesday suggesting an Army helicopter was higher than it was supposed to be when it collided with American Airlines Flight 5342 a week ago, killing all 67 people aboard both aircraft.

The National Transportation Safety Board released an update on Tuesday informing the public that the Black Hawk helicopter that collided with an American Airlines plane in Washington, D.C., last week was flying too high at the time of the crash.
