The Unholy Three of the 618th Engineers in WWII: New Guinea
WWII 5th wheel 1
Another piece of innovative engineering. They built a 5th-wheel mount to turn a Mack truck into a semi configuration, so they could tow a large crane on a flatbed trailer. This required 1-1/2 weeks work by two welders. Suspended structure in background is unidentified. Person is T/Sgt E.B. Thompson. The album page is annotated Dec 1944 but the unit history (which describes this construction in unusual detail) says the job was performed in April 1945.
