OKLAHOMA CITY / SKY LINE / OKLAHOMA / AERIAL VIEWS / AERIAL PHOTOGRAPHY / AIR VIEWS: Here's a Bomb's-Eye View of Oklahoma City. Oklahoma City's skyline is framed here in the cargo-loading opening of a C-123 assault transport as the aircraft flew recently on the final leg of a 500-hour shakedown flight. The new transport is assigned to the 309th troop carrier group of the 463rd troop carrier wing at Ardmore airforce base. Col. William C. Bentley, commander of the 309th, ordered "Operation Shakedown" to determine the capabilities of the C-123 under operational conditions in an accelerated service test.
