Shuttle One hitches ride atop a Boeing 747 to Seattle . At first that might seem counterintuitive , but Lisa Malone , a spokeswoman for NASA , says the 747 they use is stripped clean of anything in the main cabin . The load is not as heavy on the specially outfitted aircraft as you might first think . A regular plane carrying a full load of passengers is much heavier .
