Moving heaven and earth
Not content to populate the sky and the further reaches of the solar system with large things, we’re also doing it on the ground. This is the Caterpillar 777 dump truck, which is 32 feet long, 11.5 feet wide, 16 feet tall, and can haul 100 tons.
With a top speed of 40 miles per hour, it’s tires are as tall as a bus. It is not the sort of vehicle that you want to get in front of when it’s thundering (slowly) to its destination.
