On April 26, 1956, with 100 invited dignitaries on hand, one of the converted tankers, the SS Ideal-X (informally dubbed the "SS Maxton" after McLean's hometown in North Carolina), was loaded and sailed from the Port Newark-Elizabeth Marine Terminal, New Jersey, for the Port of Houston, Texas, carrying fifty-eight 35 feet Trailer Vans later called containers, along with a regular load of liquid tank cargo.
