Note the similarity of the large
buildings. Helicopters really do fly very close to the vicinity
of JPL and they actually do land in a similar location as shown
on the old picture in relation to the buildings. But the copters
are working with the Angeles National Forest and only land next
to JPL by coincidence. And there are no JPL shuttle trains, only
shuttle buses to the parking lots. Even so, they still look remarkably
similar. The building style at JPL could very well date from
the 1950's-60's so it's maybe not too surprising.

books titled "The Wonderful World"( 1954), caption
reads: "A city of the future that is quiet, clean and easy
to get about in."
