This video is actually not as impressive as the story behind it. By the time airborne photographers arrived, the semi tractor involved had been slowed by spikes on the highway laid down by police.
At a truck stop near I-75 south of Atlanta, a driver noticed someone making off with his tractor (which is what the machine is called that pulls the trailer). Instead of calling it in right away, he scrambled on board, apparently forgetting that he was not in a Hollywood chase movie. For whatever reason, he had to scramble onto the back of the rig and hang on.
From there, he called police on his cell phone.
The chase proceeded on side roads and eventually onto the interstate ... for 70 miles.
Eventually, police laid down star spikes, blowing out the tractor's tires and which slowing the pursuit considerably. The driver was able to jump off.
In the video, you will also see surveillance video of the drive rushing out of the truck stop convenience store when he sees his truck leaving without him.
