Entrepreneurs' memento mori
Rotary Rocket was a rocketry company headquartered in a 45,000-square-foot facility at Mojave Airport that developed the Roton cone-shaped launch vehicle in the late 1990s as a fully reusable manned spacecraft. Roton was intended to sharply reduce costs of launching payloads into low earth orbit. A full-scale test vehicle made three hover flights in 1999, but the company ran out of funds and closed its doors in early 2001.
