Am I the only one that wonders where the put the cranes when they have to add another section of scaffolding to raise the cranes to build the next section? Softly creeping through Empty hallways decades old, glimpsing history.

It could be the adjacent crane lifts the crane so they could place the new sections inside, or as I saw on a doc on youtube the crane can be fitted with hydraulic legs that lift the whole assembly as the crane itself helps install a new section of tower.
Cool video by the way. Exploring the distance between points A & B.

Only took 2 years to build the original towers
correction : construction of the towers started in 1966, 1 wtc was completed in 1970 and 2 wtc in 1971 and were only ready to accommodate tenants in 1973.
so it took 4-5 years for the structure to be built. Create don`t destroy.
