NTSB investigator J. Todd Inman said the Black Hawk was flying at an altitude of 325 feet at the time of the collision, based on the preliminary data they have collected.

The tower cab data showed 200 feet near the time of the accident, according to Inman. There is a 200-foot ceiling for helicopters in that corridor above the Potomac River.

The investigator said more info needs to be collected to determine the discrepancy.

J. Todd Inman, an NTSB investigator said there were five air traffic controllers working at the tower during the time of the collision.

At this time NTSB has interviewed three of the five employees and plans to interview the other two members by Monday, he said.

"This is a controller's worst nightmare,' he said. "These interviews take a long time."

The Army identified the third soldier on the Black Hawk helicopter as Capt. Rebecca M. Lobach.

Lobach served as an aviation officer (15A) in the Army from July 2019 to January 2025 and had no deployments. She was assigned to the 12th Aviation Battalion, Ft Belvoir, Virginia.
