The big rig in this video isn’t hauling a regular oversized load. In fact, it’s hauling Boeing aircraft parts which are apparently so big that the tractor trailers hauling them need two drivers, and we don’t mean your average driving team- this truck has one driver in the cab, and one underneath the trailer near the rear wheels.

From the video poster:

This video shows one of the unique dual-driver truck/trailer combination vehicles used by Boeing to transport aircraft wing spars to the Boeing assembly facility in Everett, Washington. The first driver, as with any other truck, is in the “front” cab. You can see the second driver in his cab underneath the trailer, just in front of the rear wheels.

This clip, which is from 2010, is a little old, but still so cool we couldn’t help but share.
