Note the alignment cables. With shorter and less massive sections they
might not use them, but with those massive pipe sections they had what
appeared to be maybe 1" cables through 2 or more bolt holes. When they
were close enough the guys in the lower section grabbed those cables and
threaded them through corresponding holes in the lower section. At one
point you can see the two sections come together, but a bit out of line
and set on those cables. They lift it slightly and it appears to be
pulled in place. Not to take anything away from the chopper pilot(s)
who were good!
I watched Sky-Cranes set the massive air conditioners atop industrial
complexes where I worked at one time..
At the old military base N of Philadelphia I watched one of the big
choppers lift off, straight up for about what looked like 50 or 100
feet, then back up a couple hundred feet, stop, hover, go back to the
original point, and descend as if they were on tracks. They repeated
that maneuver so long, I got tired watching. That's where I shot these:

model for the group that built 5 flying replicas from scratch, but with
modern engines inside the hand made nacelles.(I think that's the correct
term)
