What an odd looking plane.
What a tragic error!
In the early sixties, I was a mechanic on the C-124 at Dover AFB, Delaware. They uses four 4360 cubic inch engines. If I remember correctly, each engine had a 82.5 gallon oil tank. We used an oil truck with a gas type nozzle to pump about 10 or more gallons per engine after a long flight. Sure liked doing a ground test run of those big engines. Fond memories.
You might not believe it but the C-124 was an development of the B-29.
