Damon Bradshaw, in the Air Force Afterburner monster truck, soars through the air Jan. 11 during the Monster Jam at the Alamodome in San Antonio. Mr. Bradshaw took second with fast lap times and freestyle performances that had the crowd of approximately 45,000 up and cheering. Afterburner's 540 cubic-inch Merlin supercharged racing V-8 engine churns out 1,425 horsepower. Mr. Bradshaw, in his 3rd season, demonstrated that he had mastered the application of power by launching the 10,000-lb vehicle more than 40 feet in the air, thrilling the crowd. Afterburner is equipped with 66" tall, 750-lb wheels and tires and has four-wheel steering. Combine that with massive amounts of power and Mr. Bradshaw can make the truck spin on a dime by turning all four wheels and spinning out.
