Footnote: The Roton ATV never made it to San Diego. While on sling load under the CH-47, the craft oscillated too much while approaching 35 kts

Unfortunately some goofball added Bell 47 background noise to the video.

Visiting with Huell Howser: Roton Rocket​

The entrepreneurial spirit is alive and well in California as Huell visits the Roton Rocket, an unsuccessful yet imaginative attempt by a private company to create the first single stage to orbit space vehicle. Theoretically, it could deliver cargo and people to space at a dramatically reduced cost as compared to today’s vehicles with its unique design allowing the rocket to take off and land vertically by using helicopter-type blades, or rotors.
