Wingfoot Express II |
(1965)
Another contender during the jet-car battle between Craig Breedlove and Art Arfons in 1965 was the innovative Wingfoot Express II, the new creation of Art Arfons' brother Walt. Walt Arfons Wingfoot Express II was the first real rocket-powered contender for the outright Land Speed Record. Others had tried this kind of propulsion before him: Fritz von Opel had powered vehicles from cars to train-sleds with solid fuel rockets, albeit without any serious LSR ambitions. Even Mickey Thompson is known to have experimented with additional power from rockets on his Challenger 1. But until Arfons' creation, none had ever seriously engineered an Land Speed Record contender around that concept of propulsion. Walt Arfons designed a car often described as looking like an Atlas rocket lying on its side. The car sure looked like it would go faster than anyone before, even a supersonic record seemed to be within reach, but eventually little success would come from the experience. The JATO rockets ("jet assisted take-off" rockets, designed to help military planes to take-off "more easily") had too short a burn time to last through the entire length of the course: even when fired in sequences (which initially had to be done manually by intrepid driver Bobby Tatroe), the rockets would usually burn out long before exiting the timing trap, the car merely coasting along (at around 400mph!), and slowing down considerably even before the end of the timing trap. With the initial 15-rockets configuration, the best top speed thus recorded was way below the record which stood at 536.71mph (average). With the addition of 10 more rockets (protruding from the sides of the "fuselage") success was still not at hand, even thought driver Bobby Tatroe reached a peak speed of 580 mph, on one pass Bobby was lucky to escape unhurt from a spectacular fire when one of the rockets dislodged and caused severe fire damage to the rear of the car at very high speed. The car, even if not an Land Speed Record holder, is surely one of the most terrific designs that ever hit the Bonneville salt flats in Utah. After the failed attempt, Walt Arfons and Wingfoot Express II did not return to the salt and it is believed that Arfons cut up the Wingfoot Express II rocket car. |
