They needed their shuttles to be transported from one point to another and for this purpose NASA unleashed one of her biggest toys ever “The Crawler Transporter”. Crawler transporters are a two tracked vehicles that transport spacecraft from NASA’s Vehicle Assembly Building (VAB) to Launch Complex 39. They were originally used to transport the Saturn IB and Saturn V rockets during the Apollo, Skylab and Apollo–Soyuz programs but now they are used to transport the Space Shuttle.
