Astrodome

The astrodome was a technological marvel for its time. Not until the eve of World War II were manufacturers able to shape Plexiglas, a rugged transparent plastic, into a dome shape. The black disc at the top is a hanging point for a sextant, so navigators would not have to hold the heavy military models.
