On August 18, 1971, a U.S. Army CH-47A Chinook (tail number 66-19023) transporting troops from Ludwigsburg to the Grafenwöhr training area crashed near Pegnitz, Germany, when a decommissioned rotor blade was mistakenly reinstalled and failed mid-flight. The aircraft broke apart in the air, killing all 37 aboard, including 33 soldiers and 4 crew members, marking the deadliest peacetime U.S. military accident in
West Germany since World War II.
