Proscenium is a solar powered supersonic earth ship, capable of circumnavigating the globe in four hours. It was designed and manufactured by Daco Aeronautics, a subsidiary of Daco Enterprises, the world leader in aeronautic engineering in the year 2032.

Although similar in appearance, Proscenium is not technically a space ship, because it is not capable of handling hard vacuum, which characterizes travel between the planets. Victor Daco gave Proscenium as a gift to Phillip Harrington in the year 2031.
