The chosen design can be described as a manned rockoon. The second Rockoon behaved in the same maddening way. The unauthorized CD "Golden Collection 2000" (2000) includes two tracks from "Rockoon" (1992). The development of the rockoon turned out to be difficult and was eventually stalled. In spite of successful tests, the rockair concept never achieved the popularity of the rockoon. "Rockoon" was accompanied by a special limited single edition CD-5. Rockoon is the forty-fourth major release and twenty-first studio album released by Tangerine Dream.
