This whole thing reminds me of a story I heard once.

A semi-truck was transporting a large dumptruck when it became lodged under a bridge due to the height of the load.

Engineers, Hwy workers gathered to determine the best way to move the truck without doing further damage to the truck. They were calculating the strength of the bridge, the weight of the vehicles, etc.

A young boy happens along the scene and says... Why don't you let the air out of the tires on the dump truck.

I don't know if it is a true story or not...
