Building a wearable rocket ship

In 1976, Jim Neidhardt put one of the first Sony Portapaks in a backpack and used a telephoto lens. Equipped with a radiomike, I roamed the streets of the San Francisco Bay Area, posing as Howard K. Martian, extraterrestrial anthropologist. In some episodes, I used a small, wearble rocket ship. I raced a cable car up California street. My construction mentor, Geo Monley (he has a Patreon), built this model in Sketchup (minus the fins and handles).
