We found these old engines down in the viaduct. The team at the airfield want a crack at getting them going again for some kind of crafts they are building. Get them over there without losing them. Chop chop, you are late!
Take the MD tractor and locate the container trailers that are parked on the dock. Once you have located one, hitch up and bring it to the first dock. You may have to reverse some of the the trailers to the target zone in order to get back off the dock.
