Now here's an aircraft that in a way makes the B-52 and the C-130 seem like kindergarteners: The Basler BT-67. True, the ancient radial piston engines have been replaced with turboprops, but the BT-67 is otherwise much like the Douglas DC-3. And U.S. manufacturer Basler is still converting old DC-3s to Basler BT-67s. The Colombian air force uses the BT-67 as a gunship and Argentina has just purchased a BT-67 for $14.3 million (no doubt including support and spares.)

The DC-3 first flew in 1935.
