June 8 (UPI) — The U.S. Air Force ordered its entire fleet of B-1 bombers to stand down over concerns of ejection seat safety, military officials said Friday.

Air Force Global Strike Command issued the order Thursday after the emergency landing of a B-1B in Midland, Texas. None of the crew involved in that flight were injured.

The Safety Investigation Board was evaluating the ejection seat components in order to recommend corrective actions.
