Last week, engineered heavy lifting and transport company Mammoet lifted a new attraction at the NASA Space Center Houston to a greater height. As thousands of onlookers watched, a 250-foot tall Mammoet crane lifted a 122-foot long space shuttle replica three stories high to its resting place atop the original Shuttle Carrier Aircraft (SCA) NASA 905, a Boeing 747. The Boeing, with its unique piggyback cargo, ultimately will become a destination for visitors from around the world. The delicate lift to the crown of the 63-foot 747 took about 40 minutes.
