Shared on Instagram by BJ Burnell, a routine afternoon on a residential New York driveway took a sudden turn when home security footage caught an unanchored trailer breaking loose from a pickup truck. As the weight shifted on top of the rig, the entire unit unhooked and began rolling away completely uncontrolled.With someone still inside the loaded vehicle and momentum building fast toward the house, a bystander on the ground had to react in a fraction of a second to intervene before the runaway load took over.
