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.

According to an investigative update, the U.S. Army helicopter may have been flying more than 100 feet higher than permitted.

The National Transportation Safety Board is examining new data that may indicate the Black Hawk helicopter involved in a fatal midair collision with American Airlines Flight 5342 near Washington, D.C.
