Lego Model of NASA Crawler 2021

Two NASA Crawlers (named Hans and Franz) were built in the mid-1960's (when I was a boy) as part of the Apollo space program. They were used to transport the Mobile Launch Platform carrying the Saturn V rockets and the service tower between the Vehicle Assembly Building and the launch site a few miles away in Cape Canaveral, FL (Cape Kennedy at the time). They continued to be used for Skylab missions and right through the Shuttle program. Today they continue to be used for NASA's SLS program. Over the years the crawlers have gone through a number of modernization retrofits as well as load bearing enhancements.
I used many NASA photos to help me design and build the Lego model. After a lot of trial and error building and rebuilding I finally "finished" it.
I made this video of the Lego model of the NASA crawler to give a little back to the Lego community, which has amazed me with it's creativity and genius.
