When a daredevil rides a bike or a skateboard off a big ramp high into the air, that’s already crazy. It’s even crazier when people drive a racecar off a ramp. So imagine doing a jump like that in a huge truck! Driver Gregg Godfrey holds the world record for the longest jump by a truck, 166 feet. He shot off the ramp at 70 miles an hour, and landed without the truck breaking apart, though it did spin while skidding to a stop. Gregg actually beat an earlier record of 62 feet, which means he’s not the only person crazy enough to try this.
