Ryan Anderson performs this death defying monster truck backflip during Monster Jam finals March 2011 in Las Vegas. I love the name of the truck Son-uva Digger which awesomely is son of Grave Digger. Don't be fooled by how easy Ryan makes it look. I have seen a monster truck back flip before but nothing this clean.
Here is another back flip performed by off course who else but Travis Pastrana's Nitro Circus truck last year at the Monster Jam. I still don't think this one was planned though.
