We used to like to ramp things. Hills, levees, whatever you could find to take off from. I launched my '69 Nova off the western approach embankment of the Jimmie Davis Bridge going ~60mph while the bridge was under construction. We never touched the downhill part of the embankment, just landed on the flat ground at the bottom, and skidded to a stop just short of the Red River.
Total damage to car: A chunk of hard clay got beween the fan and the radiator and pin-holed the radiator.
Total damage to me: One lower lip bit through when lower teeth hit the steering wheel.
Total damage to passenger: None, and his gangly a** wasn't even belted in.
