The creator of a jet-powered school bus with a 42,000-horsepower engine says he has reached a top speed of 320 mph during test runs in Nebraska. Paul Stender, a native of Big Bend, Wis., said he and his team created the jet-powered bus in Lincoln, Neb., by taking an F4 engine and building the school bus around it, CBS News reported Monday. Stender said he was clocked at 320 mph during a recent run. \"When you do a full throttle run, you hit full throttle and then the afterburner,\" he said. \"It sets you back in the seat with a couple G\'s and you just launch, and before you know it you\'re up to 300 miles per hour. It\'s really a neat feeling,\" he said. Stender said he went with the school bus design to help interest children when he and his team talk about their work at schools. \"Plus we got three seats in there so we can give rides, too,\" he said.
