Our truck disappear, killing my friend

I was playing with a friend, we had just finished repairing our truck and my friend got into it to move it ( close to a wall ), in a few seconds a metal noise and the truck disappears... with my friend, who says he is dead and is in the ground. Shortly after, the truck comes out half from the ground upside down, and ends up disappearing permanently ( i guess )

i don,t think i can ask for a truck so, just a correction pls
