NTSB finds Army chopper in fatal midair crash with plane was above altitude limit

Investigators have found that a helicopter involved in a deadly crash with a passenger plane over Washington was flying above its height limit. The helicopter's altitude-measuring instrument was also inaccurate. These findings were revealed during the first day of National Transportation Safety Board hearings. The crash, which occurred in January, killed 67 people. The board is examining how the Federal Aviation Administration and the Army may have contributed to the incident. The hearings will continue for three days, focusing on military helicopter routes, collision avoidance technology, and air traffic controller training at Ronald Reagan National Airport.
