Rapid Paths of Progress

Fresh on the heels of the HD11G coverage from the other day comes this 1950’s Allis Chalmers crawler tractor promotional film. There is some great footage contained within regarding the construction of the Air Force Academy in Colorado Springs, The Saint Lawrence Seaway, and the Illinois Toll Road to name a few. The AC machines are the stars of the show but there is more than enough vintage equipment, trucks and cars in nearly every shot to keep fans of any brand happy. The boulder pushing scenes around Lake Tahoe are particularly awe inspiring yet terrifying at the same time. Enjoy!
