It appears the AERA website has been moved to a new domain under its true company name, AeraSpaceTours. Copies of animations and images are available on this site. AeraSpaceTours appears to be an operator, much like an Airline company. The designer and manufacturer of the Altairis is being built by a different company, Sprague Astronautics Company, Inc.
While the company has been highly secretive regarding its internal activities, some sources outside the company claim that the design of the Altairis was begun in the late 1990's, and that SACI has completed significant hardware testing.
