[1] Darrell Romick originally estimated that the craft would cost about the same as an intercontinental B-52 bomber.

[2] The concept was introduced in 1954, before the dawn of human spaceflight, to be displayed at the annual conference of the American Rocket Society.

The craft was to contain three stages, of which only the uppermost, containing the crew, would ultimately be propelled to orbit around Earth.

[2] The craft itself would have been impractically massive for the time period; however, the design ignited public interest in that it was an early concept for a reusable vehicle to transport crew and cargo to space and back,[1] and was the subject of an article in the December 1957 issue of Popular Science magazine.

[2] The original concept envisioned the craft launching from the White Sands Missile Range.
