Those pictures brings back memories. We had these Moto Tugs on aircraft carriers back in early 1950's when I was in the Navy during and after the Korean war. We called them "plane tuggers" as they were used to tow and push planes around on the flight deck. I can remember one time during the Korea war, two of the Moto Tug drivers decided they would dare who could race up the flight deck an stop within five feet of the forward deck edge. These two crazies started at the fantail (aft) edge and race to a chain cable that was stretched across the front deck. The one that stopped at the chain won. It seems one driver didn't apply the brakes when he should have and went right off the deck which was some 110' feet above the sea right into the blue Pacific ocean, which was about 2700 feet deep. Needles to say that was the last time anyone tried that stunt.
Here are a few showing the color and, etc. Would love to have my old AD Skyraider back.
