This story relates back to the time I was unloading pallets of sand blasting slag using a skid steer with forks. The flatbed trailer truck was parked in a spot where the ground sloped slightly upwards on each side of the trailer. While backing upslope with a pallet, it didn't take long for gravity to kick in once the pallet cleared the trailer deck. The machine couldn't offset the weight of the pallet and everything tipped forward. As I was jettisoned from the seat, I flew past a fasten seatbelt warning sign. The flight was cool but short, eventually being interrupted by the metal ROPS of the machine. At one point in my life I stood 6'5" however this event reduce the package to 5'7" and gave me a neck and face like E.T..
