Heard a story from a retired maintenance worker... His job was replacing light poles that had deteriorated on a military base.
At any rate the new poles were metal and weighted about 600 pounds. They were loaded on a metal frame above a pick-up truck. Once unloaded, they would use a bucket truck and some rope to lift the pole into position then they could be pushed around to line up some bolts ... they were attached above a concrete pad.
At any rate the Government pick-up trucks had cameras that faced into the cab and also forward. They would be activated by G forces to save about 30 seconds worth of video during any event such as as sudden acceleration or braking. Long story short to unload this retired maintenance worker untied the poles and lined up the truck to the unloading area and proceeded to pull forward. Then he backed up fast slamming on the brakes causing the truck to stop and the pole to unload. It went exactly where it was supposed to go!
At any rate, shortly after, they all had a safety meeting, and he saw the pole from the camera forward of the window and noticed the truck backing up then the pole was just gone. Everyone laughed. After the safety meeting the maintenance worker was called into a meeting with the big bosses and chewed out about this...
He told big boss, "if I had the same project to do again, I would unload it the same way. It went exactly where I wanted it. How else am I going to unload a 600 pound pole?"
