This Semi Trailer is So Big is Has a Second Driver in the Rear

Get ready for the ultimate test of teamwork. This unique tractor trailer constructed by Boeing is used to transport aircraft wing spars to their construction facility in Washington. Most tractor trailers just use one driver in the front who steers the whole rig.  The drive is expected to swing wide and carefully navigate for the length and width of the rear of his vehicle as well. This trailer, however, is built to haul these massive oversize loads where one mistake would cost lives and potentially millions of dollars. So they have a second driver that steers the rear of the trailer from underneath the load.

Do you think you have the skills to pull this off with a friend?
