bit rocket: This system adapts commercially available hobby rocket unit with wireless micro-video, to document crowd formations and occupations at critical public gatherings.

Launching live from street location, BIT rocket is able to reach a height of over 600ft before parachuting safely back to crowd. Rocket transmits a clear video stream to a local ground receiver; can be webcast live to web sites. Documenting actual crowd attendance, BIT rocket provides demonstrators with accurate participation figures; active strategic data [location and containment strategies of opposing forces]; and a family aero-portrait. Crowd estimates typically vary by a factor of 10; BIT rocket evidence supplies a decisive resolution. Supplements or contradicts conventional media coverage.
