It is estimated that by the time these rollers had completed the first runway and hardstand areas, they had covered a distance of 119,000 miles [192,000 km], equivalent to five times the distance around the world.
Selleks ajaks, kui teerullid lõpetasid töö esimesel lennurajal ning lennukiparklas, olid nad arvutuste kohaselt läbinud 192000 kilomeetrit, mis tähendab viit ringi ümber maakera.
