A few years ago the old Mildford, NJ papermill was demolished. While not super historic, the mill did have some architectural features that people wanted preserved, in particular, the two brick chimneys.
The demo crews wanted to just blow them up but preservationists protested and blocked them. At great expense, the chimneys were carefully lifted intact and placed in a special truck to carry them to their new destination in Kearny, NJ.
Everything went exceedingly well up until the truck driver popped the clutch too hard and the stacks fell out and broke into a million bricks.
The overall demolition was quite a project with heavy equipment turning a once thriving papermill into a giant sandbox in just a few weeks.
