Probably one of the worst things that could happen to you at an airport is the plane malfunctioning before it even takes off. If such an unfortunate circumstance ever does happen, you want to make sure you aren't stranded out on the tarmac all day. The Mercedes Unimog is designed to take care of this scenario by towing the plane back to the departure deck.
The Mercedes Unimog is powered by six in-wheel motors, which gives it the strength to be able to pull a 747. The body of the vehicle gets its look from reptiles, while the cockpit was fashioned after a fighter jet. Knowing this thing existed, I'd almost wish for my plane to break down so I could see this bad boy in action.
