The C-97 "Angel of Deliverance" is a restored Boeing C-97 Stratofreighter, originally designed as a military cargo aircraft. Introduced in the late 1940s, the C-97 was used primarily for troop transport, cargo, and medical evacuation during the Korean War and beyond. The "Angel of Deliverance" is a particularly famous example, restored by the Berlin Airlift Historical Foundation. It serves as a flying museum and tribute to the Berlin Airlift and Cold War history. With its distinctive double-bubble fuselage and robust transport capability, the C-97 played a significant role in mid-20th century military aviation logistics.
